Mutations in both copies of a gene called ACTL6B lead to autism, epilepsy and intellectual disability.

A trove of DNA sequences from 141,456 people — and counting — offers an unparalleled look at genetic variation.

A new study highlights the challenge of distinguishing genetic variants linked to autism from those associated with cognitive development.

Even as a small child, geneticist Elise Robinson wondered why people think the way they do. Today, that question informs much of her autism research.

Rare mutations in a gene called BAZ2B are associated with various conditions of brain development, including autism.

A new resource details the genetic diversity of people in Asia and may shed light on genetic conditions such as autism.

Autism may stem from a different — and larger — set of genetic mutations in women than it does in men.

The question of autism’s heritability is compelling for researchers and laypeople alike, but many people in both groups misunderstand its definition.

Mutations in a gene called ZNF292 lead to a variety of developmental conditions, including autism and intellectual disability.

No diet is likely to treat autistic people on a large scale, but diets based on a genetic profile may bring big benefits to a few.
