Larger brains may be associated with regressive autism, but only in boys, according to a study published online 28 November in the Proceedings of the National Academy of Sciences.

The rise of whole-genome sequencing is likely to result in a deluge of lawsuits against doctors for misinterpreting disease risks, two lawyers caution in an essay in Slate.

HMGN1, a protein that regulates gene expression, leads to social deficits and hyperactivity when expressed at elevated levels in mice, according to a study published 9 December in the Journal of Biological Chemistry. This effect may result from HMGN1 dampening MeCP2 expression, the study suggests.

Researchers have uncovered cellular abnormalities in Timothy syndrome by regenerating neurons from individuals with the rare autism-related disorder, according to a study published 27 November in Nature Medicine.

A new technique efficiently screens for compounds that enhance or inhibit the formation of synapses, the junctions between neurons, according to a study published 25 October in Nature Communications.

Individuals with autism-linked variants of a language gene use regions in the brain’s right hemisphere, rather than the left, to process language, according to a study published 10 October in The American Journal of Medical Genetics Part B.

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

Duplication or deletion of four genes within a large chromosomal region linked to Angelman syndrome and autism could lead to developmental disability or language delay, according to a study published in the October issue of Human Genetics.

In the brains of some individuals with autism, chemical changes to histones, proteins entwined with DNA, tend to show up near genes linked to the disorder, according to a study published 7 November in the Archives of General Psychiatry.

A drug that blocks a type of receptor at the junctions between neurons reverses repetitive behaviors in a mouse model of autism, according to a new study.
