Three variants of DISC1, a gene implicated in schizophrenia and autism, may disrupt the formation of new neurons in the brain, according to a study published 17 November in Neuron.

Intellectual disability is more likely to be associated with multiple, large or non-inherited duplications and deletions of DNA than is autism, according to a study published 7 November in PLoS Genetics.

Despite funders’ requirements to share mouse models after publication, many researchers hoard the animals for the good of their labs — and that could have an adverse effect on the field as a whole.

Researchers have identified 12 duplications or deletions of DNA regions that are transmitted along with autism in families with a history of the disorder. The results were published 7 October in PLoS One.

Studying the cellular and molecular mechanisms that underlie autism is crucial to advancing our understanding of the disorder, says neuroscientist Eric Kandel.

A subset of people with autism have genetic and biochemical abnormalities in a sleep-related enzyme, according to research presented Friday at a satellite conference of the Society for Neuroscience annual meeting in Washington, D.C.

Duplications and deletions of genetic regions linked to autism are rare in individuals referred for genetic testing, but occur at a higher rate than in the general population.

Researchers have identified autism-linked mutations using a technique that can detect deletions or duplications of DNA spanning a single gene.

The largest and most ambitious genome-sequencing project to date aims to identify rare variants and study their association to disease traits in 10,000 people.

Children with autism carry many more spontaneous point mutations in genes expressed in the brain compared with their unaffected siblings, according to unpublished findings presented Monday at the World Congress of Psychiatric Genetics in Washington, D.C.
