Deleting KCTD13, a gene in the autism risk region 16p11.2, has little effect on brain or head size in mice — contradicting results from a 2012 zebrafish study.

Male mice with a genetic variant tied to autism may have learning difficulties that females with the variant do not.

A drug that has shown promise for treating fragile X syndrome may ease features of another condition associated with autism.

A mouse model of autism reveals sex differences in brain function and behavior, incontinence and autism often co-occur, and a new literature search engine summarizes neuroscience hits into interactive visuals.

People with autism who have rare, damaging mutations tend to have low scores on intelligence tests.

A cannabis gel may ease features of fragile X syndrome, omega fatty acids show promise for autism in two trials, and oxytocin reinforces social behaviors through the brain’s reward pathway.

Children with autism may have an excess of spontaneous mutations in DNA that controls the expression of autism genes.

Scientists this week announced the release of nearly 7,000 whole-genome sequences from a collection of families that each have one child with autism.

Music therapy proves ineffective for autism, brain structures differ with 16p11.2 duplications and deletions, and mice missing NLGN3 may influence the sociability of their littermates.

People who carry risk factors for autism but do not have the condition tend to have slightly fewer children than average, and have them later in life.
