An unusual brain response to sound may distinguish children with mutations in SCN2A, a leading candidate gene for autism.
As the list of autism candidate genes grows, some mouse models of the genes turn up in long-forgotten studies.
A large study of minute mutations in people with developmental conditions, including autism, has uncovered 200 potential risk genes.
About 8 percent of non-inherited mutations in people with autism occur in only some of the body’s cells, according to a study of 20,000 people.
Families need more support from researchers in order for their heroic efforts to be optimally effective.
Two candidate genes have risen to the top, and may help scientists understand what autism really is.
A massive sequencing study spanning seven countries links 38 new genes to autism and developmental delay.
Some mutations in a gene called SCN2A make neurons less excitable and are linked to autism; others have the opposite effect and may cause seizures during infancy.
Harmful mutations in autism genes crop up in Chinese individuals about as often as they do in people of European ancestry.
