Autism and schizophrenia could be genetic opposites

on December 10, 2009

Researchers found four regions in the genome which dramatically affect the risk of autism or schizophrenia. Called “copy-number variants”, these are stretches of DNA with seemingly accidental duplications or deletions. Crespi’s team found that the presence of a particular variant – a duplication, say – was often associated with autism while the opposite variation – a deletion of the genetic material – was linked to schizophrenia.

Bernard Crespi says “The results fit with other evidence that autism may be caused by overdevelopment of specific brain regions and schizophrenia by underdevelopment”
