Further gene mutations linked to autism risk
Date:6/26/2009

ic complexity, in which many different gene changes may contribute to an autism spectrum disorder.

Hakonarson and co-author Maja Bucan said the latest findings reinforce the view that multiple gene variants, both common and rare, may be interacting to cause the heterogeneous group of disorders included under autism spectrum disorders. "We are finding that both inherited and new, or de novo, genetic mutations are scattered throughout the genome, and it is becoming clear that different combinations of these variations contribute to autism susceptibility," said Bucan.

The Autism Genetic Resource Exchange (AGRE), a program of Autism Speaks, provided genetic biomaterials and clinical data from families that have more than one family member diagnosed with an Autism Spectrum Disorder. Blood samples donated by children and their families at CHOP were used as healthy controls. AGRE makes data publicly available to qualified researchers worldwide.
