Developmental delay, intellectual disability and behavioral issues are common among people who have mutations in MYT1L, a gene with strong ties to autism.

New software can automatically identify and quantify mouse social behavior from videos, saving researchers time.

Mice missing a copy of the gene SENP1 have atypical social behavior likely due to a signaling imbalance in the retrosplenial cortex.

Many genes linked to autism are switched on in the brain’s glia, cells that help neurons develop and synapses form.

How chemical tags called methyl groups position themselves on genetic sequences may hint at some of the causes of autism.

Deleting a copy of the gene TBX1 depletes the fatty myelin insulation that surrounds neurons and reduces cognitive speed in mice.

Almost 60 percent of autistic people may have an average or above-average intelligence quotient, according to a new longitudinal study.

Shafali Jeste has spent the bulk of her scientific career searching for biological markers of autism. Her goal: to improve lives through early diagnosis and speedy testing of therapies.

Clues that problems with mitochondria contribute to autism have been accumulating for decades. In the past five years, a mutant mouse and a flurry of findings have energized the field.

Model mice of the subtype also show hyperactivity in a signaling pathway called mTOR, bolstering the idea that distinct forms of autism have different biological roots and may require different treatment approaches.
