Genes

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

Autistic children may be more likely than their unaffected siblings to carry mutations in genes linked to sleep.

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

Genetics may govern a person’s ability to pay attention to social cues.

Children in families with a history of brain conditions may be at increased odds of being autistic.

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.

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