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.

The field of neuroimaging will need to combine two strategies before it can find patterns of brain activity or structure unique to autism, the researchers say.

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.

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patterns of neuronal networks link different genetic subtypes of autism that have similar traits, according to new unpublished research.

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

The largest-yet study of genetic data from autistic people has identified 255 genes associated with the condition.

A novel method to evaluate the strength of the evidence linking autism to specific genes could reveal which ones are most useful to screen for.
