Genes

Atypical patterns of neuronal activity and gene expression in the striatum may characterize autism in girls, according to a new study.

Worms and zebrafish missing both copies of the gene CHD7 have disrupted cellular signaling, a dearth of inhibitory neurons and behavior changes — all of which are reversed by the stimulant drug ephedrine.

The more scientists dig into DNA, the more intricate its contribution to autism seems to be. Here, we unravel the complex genetics of autism.

About one-third of the HNRNP gene family’s 33 members may be associated with neurodevelopmental conditions, including autism.

An autism-linked mutation could make the brain grow unusually large by prompting cells to express a chemical signal better known for its connection to cancer.

Researchers have uncovered more than 1,200 new protein-protein interactions involving proteins coded for by autism-linked genes.

Children with autism traits tend to show agitation, excitability, decreased sleep and other mild signs of mania in adolescence; the association is higher in identical twins than fraternal twins, suggesting that genetics plays a role.

Many genes linked to autism, schizophrenia and neurodevelopmental delay regulate gene expression and support communication between neurons.

Activity patterns of neuronal networks link different genetic subtypes of autism that have similar traits, according to new unpublished research.
