Four autism subtypes map onto distinct genes, traits
An analysis of more than 5,000 autistic children and their siblings underscores the idea that autism can be understood as multiple conditions with distinct trajectories.

X marks the spot in search for autism variants
Genetic variants on the X chromosome, including those in the gene DDX53, contribute to autism’s gender imbalance, two new studies suggest.

Untangling biological threads from autism’s phenotypic patchwork reveals four core subtypes
People belonging to the same subtype share genetic variants, behaviors and often co-occurring diagnoses, according to a new preprint.

Genome structure could be key factor in some forms of autism
Variants in DNA stretches that do not code for proteins may alter the genome’s 3D architecture, influencing the expression of distant genes linked to autism.

Autism research hits the road
Some scientists are thinking creatively about how to collect data in flexible environments and meet communities where they’re at.

Some who lack autism diagnosis carry variants tied to the condition
The variants are associated with slight differences in measures of intelligence, income and employment, but the relationship may not be causal.

Loss of autism-linked gene dampens social interactions in animals
Mice and zebrafish missing the GIGYF1 gene show social traits reminiscent of autism, though the molecular underpinnings are unclear.

Simons Foundation clinical research head Wendy Chung to lead Boston Children’s pediatrics department
Chung, a clinical and molecular geneticist, plans to continue serving as principal investigator of two large research projects involving cohorts of people with autism and related neurodevelopmental conditions.

New tool aims to capture full breadth of repetitive behaviors
The measure breaks the behaviors down into eight distinct subdomains — categorization that could prove useful for clinical trials, its creator says.

X-chromosome variants help explain autism’s sex bias
The rare variants are also linked to ADHD and Tourette syndrome, two other conditions that disproportionately affect boys and men.

Autism-linked copy number variants always boost autism likelihood
By contrast, varied doses of the same genes decrease or increase the odds of five other conditions, with distinct biological consequences, two new preprints show.

Everything everywhere all at once: Decision-making signals engage entire brain
The findings, gleaned from the most comprehensive map yet of brain activity during decision-making in mice, show that the process is even more distributed than previously thought.

Astrocyte networks span large swaths of brain
The networks are plastic, connect brain regions that aren’t connected by neurons and may enable long-distance communication between astrocytes, a new preprint shows.
