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.

This edition of By the Numbers plots the rise of biology-centric autism grants, a dearth of West African autism research and the lack of racial data in intervention studies.

Targeting the molecule, 4EPS, with an experimental drug may be a way to ease anxiety for autistic people, the researchers say. But not everyone is convinced.

Only a quarter of more than 1,000 autism intervention studies published since 1990 report on participants’ races and ethnicities, and just one included a Native American participant.

Tweets this week feature research about the increases in downloads and citations papers get through social-media shares, as well as findings that tie three autism-linked genes to a new point of convergence.

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.

In this edition of Null and Noteworthy, researchers replicate encouraging findings on autism and aging and shoot down a host of potential links between pregnancy complications and having a child with autism.

The connection is likely mediated by environmental, not genetic, factors, according to a new study.

Pick up threads about how remote learning can benefit autistic students, why a study about screen time deserves scrutiny and how a newly discovered form of cellular communication could yield clues about autism.
