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

The overproduction of proteins in brain cells called microglia causes social impairments, cognitive deficits and repetitive behavior in male mice, a new study has found.

Lowering the levels of a protein called tau, best known for its involvement in Alzheimer’s disease, improves behavior in two mouse models of autism.

Deletions and duplications of long stretches of DNA may increase the likelihood of autism in people who have a mutation in a gene called PTEN.

Blocking one form of an enzyme implicated in autism eases unusual behaviors and seizures in mice missing a top autism gene.

Autistic people who carry mutations in a gene called PTEN have distinct behavioral and motor problems.

Injecting cells called interneurons into the brains of a mouse model of autism restores typical social behavior. But the reason for this effect is a puzzle.

A molecule made by mitochondria, the energy factories of cells, might help doctors forecast the impact of mutations in a top autism gene.

A compound derived from cruciferous vegetables, such as broccoli and kale, might limit the impact of certain mutations in an autism gene.

A website called GeneMatcher has helped researchers identify a new gene for intellectual disability, developmental delay and autism.
