Genetics: Study further implicates rare CNVs in autism

by  /  2 May 2012

Individuals with autism are more likely than controls to have small, rare duplications or deletions of stretches of DNA in genes that play a role in dampening signals in the brain, according to a study published 2 April in Molecular Autism.
