Skip the ritalin, get a genotype!!
This week in the American Journal of Psychiatry there is a study which links a specific haplotype(a few changes in the same copy of a gene) to ADHD onset. It is a confirmatory study(which is needed to draw any conclusions). The gene in question is the dopamine transporter DAT1. There has always been a familial risk of ADHD with identical twins being 70-90% likely to have the disease if their twin is afflicted. So naturally we have thought that this disease is primarily genetic. However, until lately the data did not indicate a significant role in DAT1 changes. But this literature is not very strong. Now there is a significant study, but this too needs some further investigation. Do I go out and get my kid tested for DAT1 polymorphisms? No. Does it give us hope for early identification of ADHD and other therapies besides a stimulant that stunts growth? You bet it does. Are there other ways to get ADHD without this gene change? You bet there are. That being said......
If there is a test and it is useful I will be the first to let you know.
Would you take the test?
