People whose brains look like those of people who carry autism-linked copy number variants also share markers of heart health.

The approach improves the function of SYNGAP1-deficient neurons in vitro, but whether it will work in people remains unclear.

UBE3A, a key gene associated with both autism-linked conditions, can explain most — but not all — of the syndromes’ atypical neuronal properties.

The drug, welcomed by patients, might be just the first of many.

The most comprehensive study of neurodevelopmental conditions in Kenya and South Africa ever conducted shares preliminary results and lessons.

The U.S. Food and Drug Administration plans to make an approval decision on the first-ever drug for girls and women with Rett syndrome by 12 March.
