Deletions within a specific segment of chromosome 22 may raise the risk of autism.

The landscape of chemical modifications on the DNA of people with autism could reveal clues to the condition and lead to treatments.

People with autism are at high risk of death from injury, China starts a clinical trial involving human embryonic stem cells, and individuals with autism have trouble seeing faces in food.

In children with a deletion on chromosome 22, having autism does not boost the risk of developing schizophrenia later in life.

Deletion of a section of chromosome 22 can cause psychosis in one individual and autism in another, via independent biological pathways.

An extra copy of a stretch of genes on chromosome 22 may contribute to autism, as well as a variety of health problems.

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

Newborn mice missing a copy of the autism candidate gene TBX1 squeak in overly simple sequences when beckoning their mothers.

Two studies prioritize autism risk genes for further research and illuminate how different types of mutations may work together.

More than 10 percent of people carry deletions or duplications of DNA that diminish their intellectual capacity. The findings, based on a large study of an Estonian population, suggest that the bigger the mutation, the more severe a person’s cognitive deficits.
