Patterns of gene expression in the brain vary dramatically between male and female mice — a finding that highlights the hazards of using only male mice to study complex disorders.

New evidence implicates the neurotransmitter glycine, which dampens brain signals, in autism.

Researchers need to consider new ways of capturing how autism manifests in girls, who may find clever ways of camouflaging their symptoms.

Two studies prioritize autism risk genes for further research and illuminate how different types of mutations may work together.

Girls with autism may show fewer repetitive behaviors than boys because of structural differences in brain regions that control movement.

A $13 million grant from the National Institutes of Health aims to help to make stem cell models of autism, and the ‘unaffected sibling’ of a girl with autism pledges to advance the field.

Elsa, the star of the movie “Frozen,” is the poster child for girls with autism.

Girls with autism are nearly three times as likely as boys with the disorder to have severe epilepsy that responds poorly to medication. The findings add a twist to one of the biggest conundrums in autism: its 4-to-1 ratio of boys to girls.

Autism labels incite controversy, and a report exposes overmedication of people with autism.

One of the most consistent findings in autism, and perhaps the most perplexing, is that it affects about four boys for every girl. This gender bias has become a hot topic in autism research — so much so that Molecular Autism devoted its entire May issue to it.
