Heritability of common brain disorders

A large, wide-ranging statistical analysis comparing common brain disorders to the genomes of over one million people has found some interesting linkage.

“One of the big messages is that psychiatric disorders turned out to be very connected on the genetic level,” says Verneri Anttila, the first author on the paper and a postdoctoral research fellow at the Broad Institute. The implication is that “current diagnostics don’t accurately separate the mechanisms” for the conditions, he says, which might be a factor in explaining the struggle to find new treatments.

The study is here: Analysis of shared heritability in common disorders of the brain.
