You know what I love. I love a good story.
Magic research discovers Longevity genes, now humans live to 900. Just like Methusaleh.
Great headline. Unfortunately, this may not exactly turn out what it was cracked up to be.
From the WSJ 1 July 2010
"Scientists discover keys to long life"
"By analyzing the DNA of the world's oldest people.......They expect soon to offer a test...."
Tranlsation, here is why you should read this story about this amazing discovery, because soon you can take a test to discover if you will live a very, very long time.
Ok, this assumes
1. The study is correct
2. The statistics are correct
3. The findings are replicated
What's worse about the article is that there isn't even One Iota of, this is a preliminary and needs to be backed up.
Instead!
Instead, they say
"The free test will be available through a public website maintained by the New England Centenarian Study"
Come An' Get It!
Well, the website doesn't have the free test. But I bet it had a million hits the day the WSJ article and the press hype came out.
One may ask, as I am now, Once the afterglow fades, what will be of this test? Further, will the paper now stand the test of scientific scrutiny.
Just this week, despite the hype machine again rearing its ugly head like it did with Time's invention of the year in '08 or the blimps and Oprah. "An Age Old Problem Solved"? Really Globe and Mail?......We are met with discourse and doubt
There are some issues with the paper. Some skeptical about the effect size. Other's, like myself are skeptical because the SNP chip used for controls and cases was not EXACTLY the same. This can at times produce noise and false positive variants....
I am going to ask the hype machine again. Before running with an AMAZING Story, Mr. Hotz and everyone else in the press. Please take the time to get both sides and an analysis of the study BEFORE publishing the story.
The Sherpa Says: I hope this does pan out though, it sure would be interesting to have an estimate, in this case 77% accurate if you would live to 100. I use family history for this and it is not as accurate as 77%. Who gets that number anyways?

Death Knell to DTC Genomics?
I was sent this article 6 times in the last 6 hours by friends and colleagues.
What's the article? "Genes Show Limited Value in Predicting Diseases"
I say deathblow to the DTC Genomics, because this article points out the issues surrounding using this limited information......
"This method, called a genomewide association study, has proved technically successful despite many skeptics’ initial doubts. But it has been disappointing in that the kind of genetic variation it detects has turned out to explain surprisingly little of the genetic links to most diseases."
What are the majority of reports you can get from 23andME or Navigenics or DecodeMe?
Reports which rely on "GENOMEWIDE ASSOCIATION STUDIES"
Not that there aren't any great genome wide associations......I think of Age Related Macular Degeneration for one.......but for every great study, there are 20 crappy studies. Which, to the unskilled observer could be made to look just as powerful. And then Silicon Valley Style Hyped, to make it to market.
I repeat, the utility of GWAS studies in Public Health NEED to be studied. Just like they are with the Coriell Personalized Medicine Collaborative.
But selling this information to people at a cost of 400 to 2500???? Sketchy at best!
From the NYT article...
"These companies are probably not performing any useful service at present, said David B. Goldstein, a Duke University geneticist who wrote one of the commentaries appearing in the journal.
“With only a few exceptions, what the genomics companies are doing right now is recreational genomics,” Dr. Goldstein said in an interview. “The information has little or in many cases no clinical relevance.”
Which is why I am aligning myself with some good People from Long Island who have been shouting this from the rooftops for about it.
A great example is this perspectives article precisely about this topic in the New England Journal of Medicine this week!!! (Only 3 this time Daniel)
Useless DTC Genomics? Not exactly. Someone is making money and has some use for it.......
The Sherpa Says: A good clinician saw this coming from a mile away. Why couldn't Venture Capital? Or the Public? Or the Scientists???? Funny, I just gave the same lecture to medical underwriters for the life insurance industry on the 14th,,,,,,

The Sherpa Reaches 20,000
- The prostate cancer risk genes and Family history. Guess what? Family history doubles the risk which the genes confer. Big surprise!
- EGAPP issues its guidance on ONCOTypeDX. Close to ready for prime time. MammaPrint, too soon to tell.
- Six new genes and Cholesterol? Get the genetic tests? No. Go get your cholesterol checked.
- Searching for your ancestry? Wind up finding cancer! If this happens to you give Helix Health of Connecticut a call
- The Gene Count drops to 20k! Should be easy for Google to catalog that.
