After imposing a pause in November 2020, the U.S. Food and Drug Administration has cleared the way for a clinical trial of a gene therapy for Angelman syndrome.

Autistic children from low-income families are diagnosed about eight months later than their wealthier peers, a new analysis of insurance claims in Virginia shows.

A drug that helps promote gene expression reduces repetitive behaviors and improves memory and sociability in a mouse model of autism.

Children born to people given an epidural during labor do not have an increased chance of having autism, according to two new studies.

Autistic people have a higher-than-average chance of developing a neurodegenerative condition, according to a few studies. Some scientists are searching for proof — work that could also improve care for older autistic adults.

Spontaneous genetic mutations contribute to autism in 30 to 39 percent of all people with the condition, and 52 to 67 percent of autistic children whose siblings do not also have the condition.

The stubborn lack of treatments for fragile X syndrome — a leading cause of inherited intellectual disability and autism — is spurring researchers to revise clinical trial techniques and revisit old drug candidates.

Some types of restricted and repetitive behaviors become more prevalent among autistic children and teenagers over time, depending on their age and intellectual ability, whereas others decrease.

An advanced DNA-sequencing technique has identified gene-damaging mutations, some with ties to autism, in about 1 in 15 men.
