A new computational method sifts true mutations from spurious ones in a single cell’s genome.

Researchers are studying how a combination of genetic ‘hits’ may contribute to autism’s diversity.

No genetic test can say whether a person has autism, but it may point to a cause for the condition or for any related complications.

Two new studies point to the possibility of detecting autism mutations before birth — along with all the ethical and logistical problems that may bring.

People with autism and their families can be important partners in understanding the genetics of autism by agreeing to share their genetic data.

Certain repeated stretches of DNA that are linked to the expansion of the primate brain may also enhance autism traits.

A pair of maps that depict variation in the human genome may help reveal the genetic roots of autism.

Finding a mutation linked to autism traits can have life-changing consequences for autistic individuals and their families.

Many countries in Europe are reckoning with the growing demand for genetic tests for autistic people — and the accompanying ethical and scientific considerations.

Genetic tests for people with autism are far from routine and don’t always yield results, but the information they offer can change lives.
