Genes

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

A group of the world’s leading geneticists is calling for a moratorium on the editing of DNA in human embryos.

Problems with the minute ‘factories’ that yield energy for cells — the mitochondria — may contribute to learning problems and other traits of fragile X syndrome.

Scientists have created five monkey clones, all carrying an edit to a specific gene.

An experimental compound that blocks two enzymes involved in gene expression improves social behavior in young mice.

An analysis of four mouse models negates certain assumptions underlying the signaling imbalance theory of autism.

An analysis of DNA from more than 20,000 people with autism identifies 12 regions in the genome that harbor inherited risk factors for the condition.

Two independent sets of mice missing a copy of SETD5, a top autism gene, link the gene to the condition’s traits.

People with autism may show scant activity in a poorly understood molecular process thought to regulate gene expression.
