Rare or common, inherited or spontaneous, mutations form the core of autism risk.
Parents of children with rare autism-linked mutations are banding together for support and to join forces with scientists, accelerating the pace of research.
Two new studies point to the possibility of detecting autism mutations before birth — along with all the ethical and logistical problems that may bring.
People with autism and their families can be important partners in understanding the genetics of autism by agreeing to share their genetic data.
Certain repeated stretches of DNA that are linked to the expansion of the primate brain may also enhance autism traits.
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.
An experimental compound that blocks two enzymes involved in gene expression improves social behavior in young mice.
