Neurona Health, a company in San Francisco, California, backed away from part of its newly launched services after Spectrum started reporting about them.

The drug suppresses an overactive signaling pathway implicated in tuberous sclerosis complex.

Genetics strongly influences some aspects of the monkey’s social behavior, including tendencies to solicit grooming and sit or play alone.

Mutations in a newly identified protein complex that interacts with the Rett protein also lead to a Rett-like condition in mice, researchers say.

Mutations in the autism-linked gene PAX5 underlie a range of traits, including developmental delay, intellectual disability, seizures and autism.

The fact that autism seems to affect more boys than girls is often attributed to diagnostic gaps, but the skew remains largely unexplained. Some scientists are turning to basic biology for answers.

Activating the immune system blunts social behavior in mice missing a copy of the autism-linked gene SHANK3, according to a new study. Blocking TRPV4, which encodes an ion channel involved in inflammatory responses, can reverse this effect.

Mutations in all three accelerate the maturation of inhibitory neurons, which could upset the brain’s balance of excitation and inhibition early in development.

Model animals don’t develop the usual behavioral and motor problems when reared in an enclosure containing exercise wheels, toys and treats.

Some copy number variants may boost a person’s chances of having autism, but to a lesser extent than previously thought.
