Genes

People who have a mutation linked to autism plus a second genetic glitch tend to have more severe symptoms than those with the mutation alone.

Genetic variants across the genome contribute to about 8 percent of the risk for certain developmental conditions — much more than previously thought.

Variants that control gene expression are often involved in whether a mutation ends up being harmful, and how harmful it is.

Many drugs for fragile X syndrome have failed in large clinical trials, but candidates that target new aspects of the condition may fare better.

A pioneering project is showing how, 17 years since the first draft of the human genome, our genes are giving up their secrets and bringing hope to parents around the world.

A new behavioral test in zebrafish may help researchers zero in on the biology of social interactions.

A new study reveals a ‘master regulator’ of many of the hundreds of genes linked to autism.
