A gene that raises the risk of autism in some people may also give humans an evolutionary boost.

Humans may be uniquely prone to rearrangements of chromosome 16 that lead to autism, according to preliminary results presented Saturday at the American Society of Human Genetics Annual Meeting in San Diego.

Too many or too few copies of a segment of chromosome 16 alters the three-dimensional organization of DNA, and affects hundreds of related genes.

Too few or too many copies of a genetic region linked to autism produce similar effects on intelligence and social skills but opposite effects on brain structure.

Teens and young adults with autism are about three times more likely than those without the condition to have type 2 diabetes.

A third strain of mice carrying an autism-linked mutation captures the nuances of this structural mutation in people.

In a feat of genetic engineering, researchers have found a way to recreate DNA duplications and deletions in human stem cells.

The brain enlargement seen in many children with autism may reveal hints about the condition’s causes.

A U.S. task force solidifies its stance on screening, a new journal promises a painless publication process, and a tiny mouse house may have a big impact.
