Patterns of DNA tags mark candidate genes for autism
Children with autism who carry mutations in the chromosomal region 16p11.2 or the gene CHD8 — two of the leading risk factors for autism — show distinct patterns of chemical tags on their DNA.

Long-term study shows language’s role in easing autism features
Difficulties with social communication appear to wane as toddlers with autism mature into young adults, perhaps due in large part to improvements in language ability.

Small head, speech delay characterize mutations in autism gene
Children with mutations in a gene called DYRK1A, a leading autism candidate, have a distinct set of features, including intellectual disability, speech delay, motor problems and a small head.

Common variants, rare mutations combine to shape autism risk
Children with autism inherit a greater burden of common genetic variants associated with autism than would be expected by chance. These variants combine with rare, spontaneous mutations to boost autism risk.

Ketamine targets lateral habenula, setting off cascade of antidepressant effects
The drug’s affinity for overactive cells in the “anti-reward” region may help explain its rapid and long-lasting results.
