Genetic Causation Of ASD Appears To Be Highly Diverse; Thoughts On Why Fewer Girls Have Autism
Sunday, Jul. 24th 2011 3:40 PM
A clinically extensive and mathematically powerful study of 1000 families with one autistic child and one unaffected sibling has validated a controversial theory of autism’s complex genetic causation. The study for the first time estimates the minimum number of locations in the human genome — 250 to 300 — where gene copy number variation (CNV) can give rise to autism spectrum disorder (ASD).
