In the New England Journal Again! CRP genetics!

Trick or Treat..... That's Russ Altman, Disguised as a Wolf-Man!!!

First the Treat!

Ok, so I hate to say it, but I am firmly convinced that the New England Journal of Medicine has been taken over by geneticists!!! I jump for glee as I open a new edition and see genetics plastered all over it.....just like the week before......and the week before that! It is true....medicine will soon be a small sub specialty of genetics!!!!!! At least if the NEJM has their way with it!


Now for the Trick

But then I stop....pinch myself and ask "Now which company will rush to market with these findings???"""

The biggest danger to Personalized Medicine is not the lack of physician understanding. Nor is it the lack of good reimbursement systems. Nor is it the lack of education in medical school. Nor is it the lack of patient desire.

It is one thing and one thing alone.......The overselling of Genomics by corporations. 9p21! Failure to replicate!


Eager to earn a quick buck or two.....or perhaps eager to bleed cash for a few years until the tide comes in, but also willing to mend that bleed by hyping some bogus test...

This is the danger.....Why? Let me explain....


When I give grand rounds at some hospital in Connecticut I am often asked......"So do you do that 23andMe test? Isn't it bogus? Isn't most of what you do not actionable?" First I am amazed a doctor has even heard of this company...but then.....


I then have to take 10 minutes and explain what a geneticist does. I have to tell them about the several victories we have in being able to identify risk and treat disease. I have to tell him about chemotherapeutic agents targeted to tumors. I then have to tell him about the promise of gene based dosing of medications. And when I am done, they will walk away......Still thinking about these companies.....


You see, if the physician thinks that genetics is hyped up molecular tea leaves.....they are less likely to put it into practice. In fact they are even more likely to skip that article in the NEJM......By hyping, overselling genomics we are making physician skeptics. The very people we have to convince that there is great utility in personalized medicine......


When Time puts on their cover that the number one "Invention" (I say this because it wasn't invented in 2008) was the retail genomic test. I laugh because they are dead wrong and once again botched the story. You can ask Ryan Phelan, she has been selling genetic tests online since 2004. No new invention with 23andMe, just the re purposing of a research tool for clinical work....which normally takes years to happen, but in this case was rushed to market in a matter of months.....Medgadget calls this like it is TIME Magazine Panders to Google Overlords, Silicon Valley Czars, Hollywood Charlatans.......


So thank you DTC SNP testing companies.....you have set back personalized medicine about 5 years...while democratizing SNP chip data which no one can make sense of......By using celebrity and affluence you managed to convince people of the fallacy.....

But you see, doctors are pragmatic and they can smell the B.S. (Not the one issued to A.W. at Yale) from a mile away!

But the problem is, doctors aren't that nuanced and when they smell B.S. they call the whole field B.S.


So why do most geneticists speak out against DTC testing? Because it is ruining personalized medicine by lumping it in with this B.S. When will DTC learn this?

Well, one team has....That's Navigenics. They have decided to partner with Academia to study the utility of this testing. They understand it is in its infancy. Since the million dollar party in SoHo (No Navigenics doesn't have a shop in SoHo) they have realized that this is a long haul and the best way to work through this time is by proving the concept through science and an Institutional Review Board. Unlike the "Founders" of 23andMe, who instead choose to enroll children into their "study" without an independent review board to protect vulnerable children's rights....

Shout out to Coriell who has been doing the "Right Thing", since the very beginning....but I guess that's because they aren't trying to make a quick buck or 2.


So as a doctor when you skip over that Genetics article in the NEJM thinking this field is all GenoHype....stop, come see the Sherpa and we can talk about the part of genetics which is real.....



The Sherpa Says: I am dead serious. If this "it's for fun talk" keeps up, personalized medicine will be dead in the eyes of the physician....Oh and BTW, the article said that CRP polymorphsims (associated with increased CRP) alone do not increase risk of ischemic vascular disease (Heart attack or stroke), But elevated CRP levels do......Maybe genes aren't everything?????

Take that atta boy Back! Time to use sound judgement against 23andMe.

I would like to take the Atta Boy back.


Huh? Yes, the one I gave 23andMe. Yes I commended them for destroying a DNA sample and confirming that they are only testing your DNA, one time and then destroying the whole sample.

Why might I take that Atta Boy back?

Because they are acting like business people again.........

In a not so certainly socially responsible move, which was alluded to by the Girl with the BS from Yale Anne.

Wojcicki: One of the areas we've talked a lot about is pharmacogenomics--being able to say, should you take ibuprofen? Or if you have a new baby and you're flying to Europe, should that child take Benadryl, or will it make them hyper?


Why? Well, everyone in marketing knows it is WAY CHEAPER to get a previous customer to buy again, than it is to find a new customer........

In this case, that customer can "coerce" their little one to donate 2ccs of saliva and their DNA (which BTW is not that much) but could cost a ton!

Well, as Daniel points out.....The professionals who have been doing genetic testing for the last 30 years or so have gone round and round about the ethics of testing minors. The conclusion is that if there is nothing that will immediately impact their health or endanger them, it is probably not the best to do genetic testing on a child who is incapable of consenting. Even then you can not expect the damage that may be caused......this case study indicates that..nonetheless, there is a debate. Between those who care for patients.....But 23andMe never took the Hippocratic Oath.....I Did....Primum Non Nocere! "First do no harm!" Some even advocate the screen the parents for the maturity and ability to comfort their children PRIOR to testing.....That is probably the best modality to please both sides!!!!

More importantly, it is probably a moral quandary when you remove that child's autonomy in a situation where it is extremely unlikely that the results will do anything to better that child's health or well-being.

So I can hear the argument now. Well, if I learn about the parkinson disease that my child is predisposed to, I will be better able to help them prevent it....

Bul1$h!t.....Which 23andMe test can do that. And BTW.....aren't they NOT practicing medicine.....and Aren't you NOT supposed to use this information in medical decision making???
Not according to investor Harvey Weinstein....
This is a blatant attempt to get more tests in. Even worse, this is an attempt to do a cohort study on child participants without the ethical oversight.

Once again. Shame on you 23andMe, just when I thought you were coming around....I begin to realize what you are.....an unethical scientist..........



2. No special provision for those special subjects (in this case children)

Instead what you offer is a silly blurb on your Q&A board!


Can I use the saliva collection kit for infants and toddlers?
The saliva kit we provide for participation in our service is not optimized for children under three years of age. If you are purchasing a kit for an infant or toddler, it may be difficult to obtain the required amount of saliva.


This is it. I have had it.....

Every time I think you are doing something good.......you crap all over it by doing these sort of things.....essentially ideas that could only be hatched by someone who is not mature enough to handle the technology!


Here's your out.....just say your investors made you do it.........

Russ, how can you advise them that it is ok to do this???????????

From the Department of Health and Human Services


The special vulnerability of children makes consideration of involving them as research subjects particularly important. To safeguard their interests and to protect them from harm, special ethical and regulatory considerations are in place for reviewing research involving children. Title 45 CFR Part 46, Subpart D provides for "Additional Protections for Children Involved as Subjects of Research." Research that is contrary to the rights and welfare of child-subjects is prohibited. A good summary of the ethical considerations surrounding research involving children can be found in Levine (1989).

Just to remind everyone...children are vulnerable subjects and should be treated as such......not as a hassle that needs to be sedated on a transcontinental flight.......


Wojcicki: One of the areas we've talked a lot about is pharmacogenomics--being able to say, should you take ibuprofen? Or if you have a new baby and you're flying to Europe, should that child take Benadryl, or will it make them hyper?


You keep doing it again and again.....Putting a research scientist on your blog who had said that finding out if you were at risk for Multiple Sclerosis was "Fun" and having her tell who she unethically tested her kids is not exactly responsible either....

The boys do share the Alzheimer’s disease-associated APOE gene region at 100%, however. So even though we don’t know their genotypes because 23andMe doesn’t report on that gene (yet), we know the boys have the same genetic risk.

So how do you counsel that Joanna?????


The Sherpa Says: For those who have the power, they shall lose it if they don't demonstrate responsiblity.....this election will demonstrate that.....hopefully the government will be responsible and not let their citizens expose their children to risk without some consideration first. 23 and Me, get an IRB......Your actions and comments are starting to reveal your hubris....





Destroy the Sample....Save the World!

I am so very proud of 23andMe. There was some big issue with their consent and policy, in fact something I expressed grave concern about. That was the indication that 23andMe/Google would own your DNA sample.....

From their site:
With the exception of your saliva sample, 23andMe does not claim ownership of the materials you provide to 23andMe (including feedback and suggestions) or post, upload, input, or submit to the Service (collectively "Submissions")

Yes.....it was a natural conclusion. Especially when the website indicated that the sample would be the property of the company. This is the case with many other things. If you mail something to a company, the company then assumes ownership of it. In this case, I had very grave concerns that 23andMe could (not necessarily would) run other tests on your sample without your permission. Heck, they could even use it to clone you....why? The DNA was theirs, not yours. Scary at best!

But now in a wonderfully socially responsible act they include this in their informed consent.

Genetic Data: The laboratory processing your saliva sample will analyze your DNA to determine your genetic information. The laboratory will not analyze your saliva for any biological or chemical components, markers or agents other than your DNA. The laboratory will not have access to your name or your other personal information. A unique bar code will allow 23andMe to link genetic data derived from your sample to your account. After analysis, your remaining DNA and saliva samples will be destroyed.

Hooray!!! 23andMe, thank you so much for clearing that up. This was the really big issue I had with your service......there are several other little issues, including the possibility of someone else getting your DNA and submitting it to 23andMe...but heck, you guys can't control all the nefarious people out there.........yet

I know that I am tough on this company.....and for good reason.....Everyone else is cheering them on. If you have no critic, how do you judge yourself? This company is going to be around for a very long time, so I ask them to remember that they are the role model for others who will follow.....

Maybe that's why I get so mad at them.......Maybe they haven't heard Uncle Ben's quote.....

"With great power comes great responsibility"

This is even more important as the echoes of detractors starts to grow!

The Sherpa Says: It is nice to see 23andMe take this big step.......

Genetic Counselor sells suspect genetic tests!


Has anyone seen this company yet? Jordana J and Access DNA.

Jordana and the "Team" at Access DNA have a form which evaluated my extensive family history and have come up with a list of genetic tests I should be tested for......little did she know that this was a list for the Sherpa and the she as a Board Certified Genetic Counselor would have to be walking me through each and every one of these tests......Her "team" by the way is only her and some advisors.....2 of them have medical degrees, but none of them are giving advice...other than Jordana.....as far as I can tell........

So today I will call Jordana J and see if she can talk to me about some of the "recommended tests" and conditions....such as:

1. Whole Genome Scanning for Aneurysm Risk (Bogus)

2. Whole Genome Scanning for Asthma Risk (Suspect at best)

3. Whole Genome Scanning for Athletic Performance (Why not just play a sport?)

4. Stool Screening for Colon Cancer @ 575 USD a pop (Uh......family history?)

5. Whole Genome Scanning for Heart attack at 2500 USD a pop

6. Weight loss SNP testing for 424 USD.....(Maybe my pockets will be lighter)

7. SNP testing for lung cancer predisposition (What are THEY smoking?)

I hope you get the picture, these were just a few of the 37 genetic tests this board certified genetic counselor recommended I get.

The Sherpa Says: When the NSGC blasts me for pointing out that genetic counselors were never medically trained AND that they couldn't explain PgX or other medical conditions without a physician involved.....I find this....Jordana J, board certified genetic counselor going out and pushing suspect genetic tests. NSGC better get a hold of their membership. This is precisely my concern.......Does the phrase "Over your ski tips" sound reasonable? This is why physicians and counselors NEED to work together on personalized medicine, not CGCs alone on an island! Like the CGC at AcessDNA.

You gotta love it!



It's mid-morning and the day is just getting moving. We had a round up today and talked about Brugada Syndrome. I think this is a wonderful topic and it was presented very nicely. It was also a timely topic......

You see Dr. Look, an internist in Germany commented on the lack of medical training for human geneticists. I think he is right. In the US, Human Geneticists are PhDs whereas Medical Geneticists are Physicians who have extensive clinical training. Yet, when genetics is taught in medical school (In year one and never again) it is invariably taught by Human Geneticists.


So why is this important? Brugada Syndrome is a condition that causes dysfunction in cardiac ion channels. This pathophysiology underlies the clinical manifestations of Brugada syndrome (cardiac channelopathy). In 10-30% of patients and families, mutations in the gene SCN5A, encoding the cardiac voltage-gated sodium channel Na1.5, have been reported. It causes deadly heart rhythms. Most people present with sudden death while sleeping or resting.


More importantly the disease often occurs in adults. Most likely in 30-50 year old men in a sex skewing of 8:1 penetrance. This doesn't mean women never get it. In fact they may have the mutation but never dies of sudden death. But here is the bigger issue.......why aren't geneticists seeing this condition? In rounds today, the other geneticists said "If this disease is 1 in 2000, why aren't we seeing it? That is way higher than NeuroFibromatosis or metabolic diseases!"





They are correct. Even Long QT syndrome which is 1 in 7000 is seen more often in cardiogenetics clinic. Long QT presents in childhood and sometime early adulthood.





I have the answer....... Brugada Syndrome presents as an adult condition. Most adult doctors don't even know genetics is a specialty, so why would they refer the patient? Heck, they do hemochromatosis testing for patients, so why not add this into their repertoire???


Here's why.....the gene can have several implications for family members and internal medicine doctors are notorious for the 1 patient 1 doctor philosophy.......


We aren't just testing the patient when we do a genetic test. We ARE testing the WHOLE family!

I find this crazy that these patients are a rare bird/Zebra in cardiogenetics clinic where they deal with genetic conditions and the heart. Why?

They are likely not being identified by anyone. Yet they are seen in 1 in 2000 people, much higher than some "Common MonoGenic Diseases"

What is even more funny is that at my residency program at a sleepy 190 bed hospital, I diagnosed 2 of these by EKG and identified 2 family members by testing. In ONE YEAR..........

In fact one of the cases had been identified as having a heart attack. The whole pathway to give this patient blood thinning medication had been started. But on EKG, the diagnosis was clear. the pathway was stopped and the patient was diagnosed. But I wonder how many times people like this get a cardiac cath. You see, the EKG finding can look like a heart attack can on EKG.....

After the rounds were over one geneticist commented that at least we would be able to build awareness at a grand rounds we were giving................In Pediatrics......

The Sherpa Says: We have to go and get out in the face of Internal Medicine Docs and tell them about this condition. The best place to see them is in Internal Medicine Grand Rounds and on the wards. So I tell Doctor Look and all my other IM brethren, go learn about this condition.....you may truly save a life......and THEN refer the patient to your friendly neighborhood geneticist! We are out there, just look for us.....

Reader's Points and Clarification.

Dear Sherpa, I am an avid reader of your blog and quite often marveled by your great writing style.

Today, however, I cannot resist to add another point to your list:
The sherpa says and might be right in saying so:
"7. The lack of medical training for genetic counselors
8. The lack of genetics training for medical professionals "


Dr. Look (me) would humbly like to add:

9. The (frequent) lack of medical clinical experience/training for human geneticists

Keep up the good work
Regs Dr. Markus P. Look,
Internist Bonn, GERMANY


Doctor Look,
Thank you so much for your comments. I would like to add that the street runs several ways. We have several shortcomings. In the United States in order for a geneticist to train in Medical Genetics (which is a 2 year program), you must first have 2 years of clinical experience in an ACGME accredited residency in just about any field. Most medical geneticists are pediatricians. This is a natural extension as the majority of classical genetic diseases start in childhood. However, there are a little under 100 geneticists trained in Internal Medicine. Approximately 1 in 10......

So I may agree that most medical geneticists are not Internists, but there are many who at least rotated through IM in medical school and elder statesmen who are internists who grandfathered into pediatrics. Much more clinical exposure than new graduates of genetic counseling programs....

But I do agree.....as genetics changes from a small sub specialty of pediatrics into pediatrics becoming a small sub specialty of genetics...we will most indubitably need more IM geneticists!

Linked together into a network preferably......

That's why I am up here at Yale.....

The Sherpa Says: If you don't know about the 24th specialty in medicine, how would you ever know how to refer to them? Looks like the ACMG needs to hire 23andMe's PR firm!

The Howard Stern of Genomics......

The other day I was talking with Misha Angrist, who BTW is writing a book about this great adventure known as personalized medicine....... I had been telling him about how my views had been pissing off a lot of people. He said to me "You certainly have a skill for that" indicating that my proclivity for hyperbole was what could eventually put me under.....


I resort to hyperbole when I think something is so outrageous that I need to go crazy. That's why some have dubbed me the "Howard Stern of Genomics" (Thank you Jeff Gulcher for the monniker). I am still looking for my Stuttering John.....


But in all seriousness, I see some big problems with this ecosystem. I think the problems are on several fronts and we need to attack each one. Why? Each problem in itself is not a reason to go crazy, but when I see them all in the big picture.....I gets my goat. These problems are the proverbial 800 pound gorillas that the field just doesn't want to address unless it is pout out there against their will.....


Now can you see why I have mentioned problems with:


1. DTC genomics


2. Public genome exposure of uninformed participants


3. The woeful lack of genetic competence by doctors


4. The pi$$ poor reimbursement rate for services


5. Patent protected genetic tests


6. Silly CEOs not having a grasp in reality, or distorting it to promote/hype genomics


7. The lack of medical training for genetic counselors


8. The lack of genetics training for medical professionals


9. The horrible job of reporting genomics to the public


10. The lack of reputable VC/Investment firms willing to take a hit and invest in soically responsible genomics.


11. The fear of businesses upsetting their customers by speaking the truth....





So as you can see, I have had the chance to piss off just about all of the field.....and have done so in many ways.....





Do I do it for spite?


No.


Do I do it because I dislike each and everyone of them?


No.


Do I think they are doing good things?


Yes.


Do I think we could do things better?


Absolutely..





So if you are one of the myriad of people that are upset with what I have had to say......rather than get all mad and speak ill of me at cocktail parties or try to get my friends and coworkers upset with me or any other completely destructive things you are looking to do....





Ask yourself........."Is the Sherpa right?"


If I am not....then feel free to flame me.......


But if I am right, have the guts to admit it and go about changing our ecosystem.





Yes, I AM calling you out!





-Steve

Why genetics takes time and why insurance sucks.


With all of this hubub about SNP testing, DTC ordering, the role of the physician and why healthcare is in a crisis....... I wanted to point the most serious issue. The lack of reimbursement from insurance companies.

You see, the big reason any venture capital firm would want to invest in a big DTC testing company is that they can sell something which is automatable and scalable. It is the perfect product......you see, they can collect cash day and night, 24/7, online and not have any human interaction, except when the specimen gets to the lab. Heck, they can even automate that too these days. So in essence you could spend little and collect a lot....in the biz that is what's termed a "Home Run". Not exactly socially responsible, but you can have PR firm spin that for you anyways.....


You see, that's why do it yourself genetics is great. You never have to pay for expensive doctors or counseling...why? With these social networks, people will "Google it" to figure out what the heck is going on.....in essence people will become genetic hackers.....

The most scary part of that, is the "hacker" will pass along legend and lore, medical misinformation, hence becoming dangerous to others. This is precisely what alot of medicinal quackery was prior to evidence based medicine.

This was merely observation and not subjected to rigorous scientific analysis. Even worse, these days, bad science or preliminary findings published in a "Big" journal can also get passed along "As If" it is now valid medical care. "Hackers" love that sort of thing, because it "sounds" true...


Why am I bringing this up? Because, investors don't care about evidence base or if the patient will be better because of a test. They care about getting alot for a little and making money on their investment.

So where can you have the opposite? Where you make a little for a lot?

Medicine, I mean real medicine with doctors and nurses and hard work....not exactly Do it yourself......

Why am I so down on insurance? Let me give you an example.......If I was an attorney charging per hour at 350 USD per hour versus a doctor charging insurance for a 99245 which as I told you before pays on average $256 NOT per hour, per visit...

Here is a typical medical bill, marked like an attorney's bill:


  • Reviewed/Returned email from patient 15 minutes

  • Phone call to Radiologist X who read film and reviewed with me 30 minutes

  • Reviewed chart sent by PMDs office 60 minutes

  • Literature review regarding disease X 20 minutes

  • Phone conference with PMD re: differential diagnosis and plan 20 minutes

  • Confirmed appointment with patient and discussed concerns 15 minutes

  • Appointment with patient 80 minutes

  • Total Hours 4 hours

  • At 325$ per hour and 10% Professional Discount 1170 USD

What does insurance pay? 256 USD dollars, I hope you can see why the system is failing.........

Why in the world would any VC want to fund such a labor intensive service......Insurance sure as hell tries not to. Why do I say this? Because every single other professional in the US bills and gets paid this way but not the doctors.......in fact, for every person who pays for these services we could serve probably another 1 or 2 patients pro-bono.

So what happens when a patient wants a DTC test with a doctor interpretation?

Good question....I am not certain how one would bill for interpretation of a 1 million SNP scan. I guess you would have to take a family history and look for a diagnosis....Heck, if the patient walked in the door, you couldn't even bill for a 99245, you would have to bill for an in office evaluation which pays even less than the 256$.....


But here is the problem......most patients don't want to be hackers.....most patients want to speak with a doctor......preferably a doctor who knows what the test they just took means......

So I ask you.....Is it really greedy to ask for 1000 USD for an intake? Especially when billing insurance means you can't spend the time you would like on the case, or even worse, if you do spend that time today......will you be in business tomorrow???? A classic example.....DNA Direct charges 3456 for BRCA full sequencing, yet Myriad only charges 3120 dollars. Because they don't mark up their test, the 2 mandatory genetic ocunseling sessions at DNA Direct cost 356 USD.....if insurance paid for that it would be 120 USD.....No business can afford to use insurance to reimburse for Genetic Services........period! Interestingly Myriad cuts the cost for NIH research to 2500 USD..... So one really wonders what the test costs.....I know for sure what the manpower cost for evaluation is!

The Sherpa Says: To really get personalized healthcare we need to radically change how healthcare is funded. The paper pushing...the coding....the lack of pay......they all need to go away......or heck, maybe someone could just automate all of that crap and let us get back to caring for people, NOT ICD9's.......

DTC says "Steal your baby's genome....it's fun!"


One of the big things 23andMe has emphasized in the past is that their data is not to be used to make medical decisions.....


This from Forbes when the regulatory heat was on in the spring.

Then their consent notes that their kit is not for medical use:

Furthermore, 23andMe's service is not a test or kit designed to diagnose disease or medical conditions, and it is not intended to be medical advice


Then their blog lists their terms of service which includes.......

23andMe does not recommend or endorse any specific course of action, resources, tests, physicians, drugs, biologics, medical devices or other products, ...


So naturally when I read the interview of Linda and Anne with Emily Singer at TechReview I was a little surprised....to say the least


TR: What will be one of the first examples of genetic information someone might use to make a medical decision?


Wojcicki: One of the areas we've talked a lot about is pharmacogenomics--being able to say, should you take ibuprofen? Or if you have a new baby and you're flying to Europe, should that child take Benadryl, or will it make them hyper?


Ok, Ok, this is the hype that will kill genomics. Unless I have been asleep for the last 6 months, some things have changed.


1. 23andMe is now stating that people can use their tests to make medical decisions......

2. They are moving into pharmacogenomics, but not providing medical advice

3. They are using a BOGUS example (Benadryl response) and not stating that this is not a genetic reality TODAY.

4. Lastly, the implication is that as a parent, you can test your child's genome without their consent is abhorrent and unethical. Even the remote possibility of being able to do that with their kits is scary and needs to be investigated.

This is where the straw breaks the camel's back.

Anne, are you serious? Do you really think it is ok to test your child for a hypothetical benadryl response(which has no basis in any reality out there)? Have you lost it? Have you heard of informed consent? OMG! This is crazy!!!!!

This, ladies and gentlemen is precisely why I am so concerned about what is going on with this and other companies. The CEO of this company thinks it's ok to take a swab or saliva from your child and test it for millions of SNPs just so you can dope the kid up on a trip to Europe. Most likely without their consent! Is it for any health benefit at all???? Oh, I guess we should allow parents to have their kids drug tested "just because", or force our kids to have pregnancy tests, or better yet, let's just call this what it is "Stealing your child's genome and exposing it to discrimination and risk without their consent"

You see, I knew this would come out. There is a lack of maturity at the highest levels in this company and a significant lack of concern for privacy and personal risk.

The Sherpa says: Wojcicki: One of the areas we've talked a lot about is pharmacogenomics--being able to say, should you take ibuprofen? Or if you have a new baby and you're flying to Europe, should that child take Benadryl, or will it make them hyper? I am appalled and speechless. Stealing a genome, to make a faulty prediction and expose your child to risk. I hope Linda will set this one straight......and a "No one was implying that it is ok to steal a person's genome" quote just won't cut it. This could kill DTC completely if the regulators read about this!

Uh Oh......the FDA sets the bar


In an editorial from the Lancet,

Medical groups have expressed doubts about the validity, effectiveness, and clinical usefulness of direct-to-consumer genetic testing. More harm than good is done, for example, by false reassurance from unproven genetic tests or by unreliable information that could lead patients to terminate a pregnancy or seek surgery.

These are the concerns from the field and they may be valid. They may also not be valid. Let's examine each:


1. Doubts about validity-


What exactly is valid? Is valid the genotype? Is it the validity of the phenotype which the genotype is said to "predict" Is it the validity of the studies which back up the test? In the case of genotype, I would say the test is valid. In the case of the 2 others...it clearly is not.



2. Doubts about effectiveness-


Effectiveness in what? Predicition? Prevention? Guidance of therapy. On all of these counts, the doubts of effectiveness are valid.



3. Doubts of clinical usefulness-


Well, what IS clinical usefulness? Is it, the ability to derive a new use/diagnosis from a test result? Is it the ability to put into action a clinical plan to prevent or treat disease? If it is either of these, the data is not there for most DTC tests....But I also have said that clinical usefulness could just be the ability to plan for future risk or future care. In this case predisposition testing for Alzheimer or Parkinson Disease may be useful......depending on the test and its clinical evidence....To answer this question a genetic test needs:


A. A clinical study showing predictive outcome. I.E. in a prospective manner, that would be very nice. Especially if I am to tell a patient how likely they are to get this condition and when....


B. Some clinical data showing outcomes in treating patients with genetic predisposition. I.E. in the case of the BRCA1 or BRCA2 genes.


C. Some clinical data showing that an intervention on persons with a certain SNP or mutation, prevents the prior expected outcome.



Even if we had none of these things......some may say "Why not let people buy this sort of information to do with it what they wish" That is not clinically useful. It may be socially useful, but some have real questions about that as well...


In my humble opinion, this buyer beware is a very libertarian/conservative view. Which may or may not be so bad. Unless we have harm being done to citizenry.


So, is harm being done?


Some would argue no. Others argue yes.


But these data revolve around clinically valid tests. Most importantly, almost all medical societies are against DTC testing b/c of possible harm. But some argue that these motivated genetic test subjects wishing for DTC testing, self select to minimize the harm....which could be the case. But that assumes the tests are actually valid.


So what happens when the tests do not meet the criteria above? Well, no one knows the answer. But there are a ton of ethicists who are arguing against such testing. Why is this important?


Well, put simply. Medical Ethicisists most often fall along the lines of patient autonomy. In fact alot of people debate about this principle seeming to be absolute. So if most ethicists think the patient should have ultimate choice in their care, why are they against DTC testing???? Good question.


So here we are, in a position with not much data, and we won't likely have it for several years. We have ethicists who put patient autonomy first, against DTC testing. We have doctors, against DTC testing. We have government against DTC testing. Now, with the recent FDA warnings to labs promoting tests without evidence, the writing is on the wall.


“Because you do not have marketing clearance or approval from the FDA, marketing OvaSure is in violation of the law,”


That could just as easily be any other genetic test marketed to physicians or consumers. The FDA has weighed in and DTC is likely to be in its sights. Despite their detractors, the FDA is unstoppable here.


So, the answer is simple....we all have to await clinical data and trials for a clinical tool. Is that such a stretch? Is that such a bad thing? Well, it very well may be if your investors are on your case. Or if you need to pay your bills and your university salary is paltry. Or it may be if you have a mortgage whose rates are climbing? I hope you see what I am saying.....money clouds medicine, most importantly genomic medicine.

Everything that's great comes from blogging!

Today, I want to point out what Webicina is and why it is important. You may be asking yourselves....webicina? What the heck is that? and Why should I care....

Here's why. Just about everything in my professional life has gotten light years' better since I started blogging. Some notable achievements.....

1. Invited to participate on the Coriell Personalized Medicine Collaborative's ICOB
2. Invited to speak on a panel with Navigenics, 23andMe, deCode, DNADirect
3. Inivited again to speak on a panel with Linda Avey (this one for the second time)
4. Invited to speak to the National Society of Genetic Counselors about personal genomics
5. Working on a scientific collaboration with OSU (and many others) because of blogging
6. Interviewed by Karen Shughrue of 60 Minutes and the NYT and the LA Times and MSNBC and CBS.........
7. I met some great friends
8. I have been asked by 3 web health companies to help them create genomics resources
9. I have formed 2 companies because of blogging
10. I have learned to handle the masses of people who disagree with me in much better fashion
11. I have sparked a national debate when everyone was cheering something that was not quite of value.

I could go even further but I won't b/c I want to talk about how it all started.

There was this guy named Bertalan Mesko.

He saw that I started a lowly blog back in March of 2007. He stepped in and said, "Let me help you build your blog" First you have to get HON Coded, next you have to join a group, then you should do 1,2 and 3..........Why was this important?

You see, Berci (as his friends call him) was starting his company without even knowing it. What he did for me, he had most certainly done for dozens of other blogger....the fruits of his labor are now called Webicina!

What can Webicina offer you? exactly what it offered me.

A broken watch and deCode's test

I am posting today away from home. In case you didn't know, my family is a BRCA family and a wonderful lady who was hit with not one but 2 breast cancers and metastases just passed.

I am sad today. But even with that, I am bolstered by the amount of work being done in this field. Soon we will have tests which can identify risk for non BRCA breast cancer. But that day is not today.

Why? I just finished looking over some more of the SNPs which deCode is testing for....

rs1219648 the SNP associated with FGFR2 and Breast Cancer. Published in the "Highly respected" Nature Genetics!!!

1. Populations-1142 European/Caucasian with postmenopausal breast cancer
2. Penetrance- unk, but OR was 1.23 and for Hmz 1.79
3. Function- unk, but could be a splice site variation.
4. Prevalence- Not reported here.

There was another study in Jewish (Ashkenazi and Sephardic) and Arab women......about time
Here's why it gets confusing. They cover these SNPs as a haplotype study. What's a haplotype? A subset of SNPs that are linked together. In this case, the AAGT haplotype and the AAAC haplotype. The wildtype is GGAC. You see it turns out in the AAAC haplotype puts Sephardic women at increased risk for breast cancer, but not Ashkenazi Jews. It actually reduces risk in the Ashkenazi population!!! Huh?

I hope you see what I am getting at.

"Each of the genetic markers in this risk test have been replicated in between 5 and 30 different populations in studies by deCODE genetics, the National Cancer Institute, and UK Cancer Research."

Dr Gulcher's words, not mine.

That is just not true. Some of these SNPs are protective in some and risk creating in others. That data has NOT been replicated in truth. But, if you mean replicated in the same study........then you could stretch that to maybe 5 populations. But when you say population, do you mean the few hundred women from the US Multi-Ethnic Cohort that was lumped in with the Swedes? This is the frustration I have and why I started HelixGene.

The days of silver tongued scientific shenanigans are over. I will personally read every study I can about each test and report turthfully and give clinical meaning to each study. I hope you will join me.

We have very few tools to assess risk properly in breast cancer care. But we should not put a tool in the chest which will not get the job done and that could result in improper guidance or significant medical misinformation. Clinical tools require much more refinement than one or 2 studies published in NEJM.

The Sherpa Says: Perlegen is also developing a breast cancer test. I hope they get the data before bringing a test to market. Here's a riddle, what does a broken watch and 2 of the SNPs from the deCode test have in common? Answer: They are both right, twice a day......

deCode Versus Arthur Caplan PhD.

To attempt to sort out the hype from the hope, Sherpa Style. I will review each and every SNP that deCode is using for it's Breast Cancer Test. This weekend I will cover the first 2. But first some hype from both sides.


Genetic testing for all sorts of conditions is all the rage these days. Everywhere you turn, some company is urging you to spit in a cup, take some blood or swab your cheek so your DNA can reveal your health risks, know who your long-dead ancestors are, pick the right mate or help you design a diet that is perfect for your genetic makeup. But, "spitomics" has gotten way ahead of genomics.

Sadly, the tests Decode and other companies are offering are more likely to empty family pocketbooks and leave women with a false sense of security than they are to prevent breast cancer.



Arthur Caplan stresses caution in the application of the new genetic risk tests for common diseases and I certainly agree that genetic testing should be applied with care. However, he goes too far when he says that the new deCODE BreastCancer genetic risk test is only useful for women who have two or more close relatives with breast cancer, is not based on large enough studies to be accurate, and is not regulated........Each of the genetic markers in this risk test have been replicated in between 5 and 30 different populations in studies by deCODE genetics, the National Cancer Institute, and UK Cancer Research.


These studies have been published in the most prestigious, peer-reviewed journals, including Nature Genetics and the New England Journal of Medicine. Altogether almost 100,000 patients and controls have been studied to define the marker risks. We made this test available for physicians to order for their patients through our reference laboratory which is regulated under CLIA by the US Federal government.


There are two major types of breast cancer: the rare, early onset form that occurs in certain families and for the detection (for which the Myriad Genetic test is well suited), and the common form which accounts for 95 percent of breast cancer.


Well, Dr. Jeff, you are making the case for BRCA smaller than the data shows.....So right off the bat I am a little suspect.....The number for familial breast cancer is 10-12% and BRCA has the majority of that......Oh and you do read the economist don't you? Famous is not always better buddy.

Ok, so who is right. The chances are high that they both are. But let's go to the tape!


What are the SNPs they test for? On limited weekend hours I will review 2 SNPs.


1. rs13387042 when looked up in a pubmed search only shows one article in Nature, by guess who? deCode.....still waiting for this "Well replicated SNP"

What does this SNP reveal and for whom?

Population: Icelanders, replicated on Northern Europeans (Sweden, Spain, Holland, US MEC)

Prevalence: 25% of Europeans, widely varied in other ethnicities

Function: Unknown, no genes known in this linkage disequilibrium block.

Penetrance: Unknown, OR is 1.2 for ER positive and 1.06 for ER negative

This study isolated 10 SNPs and only 2 SNPs replicated, I don't see the unreplicated ones in the paper. Importantly, this SNP did not replicate perfectly in the Swedes.... The SNP varied widely between ethnicities in the Multi-Ethnic Cohort in the US.......They observed no interaction between the 2 SNPs that replicated in Caucasians.....The effect seems that it could be recessive.....


The study even acknowledges that this was a limited effort in finding risk SNPs....."However as the relative risks remain low, they (these SNPs) can only account for a small fraction of the familial clustering of this disease.


2. rs4415084 guess what, the same thing happened with this SNP. Only one article, by guess who? deCode. This time in the Brief Communications of Nature Genetics......I look forward to the Independant Replication...


Population: Iceland first, then replication in (Sweden, Spain, Holland, US MEC). It flopped in Nigerians!

Prevalence: Not reported in this one and only paper on this SNP

Function: Unknown, but maybe linked to FGF10 which is amplified in 10% of breast cancers. Also MRPS30 is in this area....but really, we have no freakin' clue.

Penetrance: Unknown, but the OR for ER positive breast cancer is 1.27, for total breast cancer is OR of 1.14


So let me translate. These are 2 of the seven SNPs DeCode claims will help show risk of common (Read as not BRCA related) breast cancer. If this is any indication of the rest, I am sad to say that they are out on a limb here.


Several clinical questions come up when I want to order this test.

1. Who do I test? In the case of these SNPs, I would guess white women.

2. How common is this risk? Not very common in the case of Asians or Africans. In fact in one of these papers, a SNP being tested for didn't show increased risk, it actually showed protection from breast cancer.

3. How do I counsel a positive test? Tough to say. We don't know the penetrance, we know an odds ratio for a certain group.

4. Can I see deCode's data on their magical risk calculator thingy that includes these SNPs? Or is that a trade secret?

5. How reliable is this science? Not very, the studies were replicated by deCode and not by other groups.....

6. Is this "test" validated? I would love to review the seven panel test publication....oh wait, I couldn't find it.....


Not all of these SNPs are that thoroughly validated or as "replicated" as Dr Gulcher said. So this is the case of rushing to market with a test.

The Sherpa Says:

This test is Hype until proven otherwise. I await the future studies on these SNPs. Dr Jeff does a good job on deCode's blog of promoting it though. I know early detection is key and pre-disease is the new disease, but a clinician has to have confidence in their tools. This one is a little primitive for me.......and at worse could give patients a false sense of security. So guess what......Jeff and Art, you are both correct.

October and November is Personalized Medicine 2 Months!


That's right. Personalized medicine is such a hot topic that we deserve 2 months! Why Not? I will get W. on the phone and make it so!

Seriously though, there are some excellent conferences on the horizon. I was asked to speak at a couple but couldn't do it and am now pulling out of another. But don't worry, the Sherpa will still be speaking at the Burrill and Company conference in November.

W2W4

1. Ohio State University Medical Center is having its inaugural conference in Personalized Medicine. I am so sorry to not be able to attend nor speak. But we will be collaborating ;)


2. Harvard and my colleague Mike Murray are now having their CME conference on the Genetic Basis of Adult Disease. I will be speaking there and am on Faculty at this wonderful conference. I will be traveling Sunday at 2am to get there in time! Mike and Mark, Bruce and Dick will all be there! All should attend, Internists, Specialists, PAs, NPs and CGCs!


3. ASHG is in Philly. For those who don't know what (Ay-Shag) is, it is the American Society for Human Genetics and it is a must attend conference for EVERYONE. I will be flying in from San Francisco where I will speak at.....


4. The Burrill Personalized Medicine Meeting!!! Where I will be presenting with Linda Avey and Peter Vitulli from Sciona. I am super excited about this conference as well.



:( sorry Raju!!! But it is yet again, another great conference to put on your radar.


Lastly, I am sad that I will be unable to speak at the NSGC Education Conference, unfortunately a personal commitment precludes me from flying to L.A. I was so hoping to catch up with my friend Brandon Colby there, but will have to defer. Oh well, there is always next year. I was looing forward to going over the Navigenics and 23andMe reports with counselor and explain what would be needed to interpret and counsel on risks of complex diseases like heart attack and multiple sclerosis.


So you see....Personalized Medicine is so big that it deserves 2 months!!!


The Sherpa Says: Have a great Columbus Day everyone. Remember, Columbus was ridiculed by all aspects of what was considered rational society for wanting to travel across the globe. He had an idea and criticized conventional thinking. Unfortunately, his own country wouldn't support him. I kind of consider myself to be just like him. Risk taker, lightning rod and discoverer of a New World. We ARE headed to that New World. Why don't you join me? I can't wait to get there, we are already underway!!!

CGCs, NPs and Me!!! Genetics will never be the same!

After about 50 emails, it became crystal clear. CGCs think I am bashing them when I point out their limited clinical training.

They also think I am bashing them when I point out that they should not be giving advice on medications that they do not know all the side effects or risks.

They also think I am bashing them by promoting the role of nurses in clinical genomics.

Wow! I never thought this would raise such chaos! I first would like to point out what Genetic Counselors are trained in. From the ABGC competencies.

An entry-level genetic counselor must demonstrate the practice-based competencies listed below to manage a genetic counseling case before, during, and after the clinic visit or session. Therefore, the didactic and clinical training components of a curriculum must support the development of competencies that are categorized into the following domains: Communication Skills; Critical-Thinking Skills; Interpersonal, Counseling, and Psychosocial Assessment Skills; and Professional Ethics and Values.

I highlight Communication skills because of what the ABGC demands.

From the site:

Can convey genetic, medical, and technical information including, but not limited to, diagnosis, etiology, natural history, prognosis, and treatment/management of genetic conditions and/or birth defects to clients with a variety of educational, socioeconomic, and ethnocultural backgrounds.The student is able to demonstrate knowledge of clinical genetics and relevant medical topics by effectively communicating this information in a given session.

What happens when that genetic condition is stroke? What about Left Main Coronary Disease? How about Inflammatory Bowel Disease? Coumadin metabolism???? There are a small cohort of counselors who know about these topics through workshops, or perhaps working with a doctor who studies these diseases....but that is a small few......like Karen Greendale. Who BTW is doing a wonderful job of getting this group together.

I hope you see what I am getting at.....most never trained for these things, but will soon be expected to handle this........BTW, this IS genomic medicine.

I just don't see how we rationally can expect someone who hasn't worked with coumadin or taking care of patients in a telemetry unit, to explain the workings of the heart or the cytochrome p450 system without some sort of medical clinician involved. It is just not fair or realistic.

This is not bashing your profession. It is pointing out the shortcomings of inappropriate utilization of manpower. Trust me. You will have more than enough work. But when it comes to these fields, I think a little more clinical training would help CGCs carry out Genomic Medicine counseling. Is that too much to ask?

I don't think so.

I want to remind all Genetic Counselors, you are part of the solution, not the problem. Yet, the comments and emails I received were reminiscent of the 100s of emails and comments from the Silly-Con Valley types when I said that they should have some sort of genetic counseling pre and post SNP scan and when the Government agreed with ME.......You are part of the solution CGCs, I never said you weren't. I just see your role evolving, and that evolution requires change.

Despite what Drew Y at ThinkGene says, you will not be programmed away. I have never seen Python code hand someone a tissue when they are crying, or comfort them with a caring voice.

Now some comments from my wonderful readers...

Anonymous

Yes, a CGC should have a year (or two) of clinical training. When I was shadowing a GC a couple of years ago, the doctor asked the GC if she had any thoughts for what genetic condition the patient may have. The GC said: "I don't have any idea." Some GC's will continue to learn at a much deeper level than other GC's.You couldn't have said it any better: "They don't even speak the clinical language very well. In order to take accurate medical and family histories, they need to know the genetic implications of sudden death, stroke, heart attack, coumadin metabolism, protonix efficacy, alzheimer disease, COPD, I could go on and on. But if they never saw it and talked about it, how could we ever ask them to learn this stuff through Osmosis or "Clinical Workshop"?????"
The way a CGC is trained needs to be adjusted



I agree completely

I am a CGC and I appreciate your honest and well-articulated comments on our limited clinical training. CGCs have some important skills that most physicians do not. Our professional organization (http://www.nsgc.org/) defines our scope of practice very nicely, recognizing these limitations. However, CGCs are not licensed providers in most states, nor are we recognized as allied providers by CMS.


This means that our scope of practice is not regulated or even on the radar of a regulatory body. So, what happens in practice is that the role of the CGC in a given case is determined by the physician s/he works with (usually medical geneticists). The physician is in the position of being the CGC's boss, the lines are muddied, and the role of the CGC is at the whim of the MD.


This is a terrible position for the only workforce that right now DOES have the genetics knowledge to provide to patients in the age of genomic medicine.

Our scope of practice needs to be better embraced by the health care system, with our role being one of providing risk assessment, genetic testing options and educators of patients and providers. Most CGCs feel very uncomfortable discussing management, but are put in that position by geneticists who frankly rarely manage

Thanks for the comment
I agree, clinical geneticists need to stop getting on conference calls for grants or in the lab, and get their asses into the clinics and on the floors. They have failed all CGCs out there. You could have used their clinical education!

Gosh, I find it awful ironic that you BASH genetic counselors so harshly on your blog, yet have them listed on your “Helix Health of Connecticut” website in the very first sentence about the healthcare team. Do you really think that your silly attempt at an apology to your “excellent CGC colleagues” will be sufficient? And gee, while we’re talking about “clinical ineptness”, I thought I should also throw out the fact that you specifically list services such as “preconception genetic evaluation” but I see no one on your team with an obstetrics background. (Haven't updated the site yet)

I guess having someone with that type of “clinical training” wouldn’t be necessary since you’re just helping a couple plan for a PREGNANCY.

Luckily, it seems as though the only patients that are going to be able to seek your great “expertise” are the few economically elite. For the rest of the population, we’re going to have to settle for consultations with all those well-educated, compassionate, hard-working genetic counselors out there.

No one said you weren't educated or hard working. I just think you shouldn't be forced to practice medicine because no physician will work with you......simply due to the fact they have grant deadlines.....As for our fee for service practices. We do this to keep our doors open, rather than have physicians who refuse to see patients and instead put the CGCs out on an island to either bill for 60 dollars per visit or commit insurance fraud.

I repeat. Genetic counselors are a valued part of the "team". I pejoratively put out there that there wouldn't be room for you.......If you continue educating counselors the way that you have always done it this could push you away from pharmacogenomics or chronic adult disease and personlaized medicine. Listen, the same is true for pediatric geneticists. The same is also true for non-genetically educated internists......

We have to get a grip on what we can and cannot do without some sort of formal education.....because if we don't, then we will have CGCs giving bad advice about medications or adult diseases.........or Internists misinterpreting genetic tests. Can't you see that it is just as bad????

The Sherpa Says: There will always be a great role for counselors. But unless they start learning the fields most affected by personalized medicine, they will find themselves forced to do things they aren't prepared to. We have to fix the broken genetics system AND the broken medical system. Because if we don't, a whole heap of people like Drew Y will point to our flaws and try to write code to "fix" us!!
