An experimental drug silences a DNA segment and seems to prevent seizures and death in a condition related to autism.

About 6.5 percent of autistic people in the United States also have dyslipidemia, a condition characterized by abnormal lipids levels in the blood.

Repeating bits of the genome may be responsible for nearly 3 percent of the genetic architecture of autism.

Two new analyses help to explain why mutations to the chromosomal region 16p11.2 can lead to autism, intellectual disability or language difficulties.

Nearly all genes with moderate to strong ties to autism are expressed in the developing amygdala; a few show altered expression in the amygdalae of autistic people.

The autism gene SHANK3 is crucial for the development and function of muscles and the motor neurons that control them.

Brain structure of autistic people with deletions in the chromosomal region 22q11.2 differs from that of autistic people without the deletions.

A new treatment prevents seizures and improves memory in a mouse model of fragile X syndrome, according to a new study.

A new analysis links individual mutations in a gene called PTEN to a person’s odds of having autism, cancer or other conditions.

Dampening overactive brain circuits alleviates social and memory problems in a mouse model of 22q11.2 deletion syndrome.
