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.

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.

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.

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.

Scans of sundry variant types uncover autism-linked genes

Troves of sequencing data reveal genes tied to autism through different variant types, providing a more complete picture of the condition’s genetic roots and new clues to its heterogeneity.

The final frontier: Autism geneticists take on the noncoding genome

The vast stretches of DNA that don't code for proteins could fill key knowledge gaps about autism genetics. But making sense of it all won't be easy.

Common inherited variants tied to autism show sex bias in families

Siblings of autistic females are more likely to have autism than siblings of autistic males are, and mothers of autistic children carry more common, autism-linked variants than fathers do.

Seeing the world as animals do: How to leverage generative AI for ecological neuroscience

Generative artificial intelligence will offer a new way to see, simulate and hypothesize about how animals experience their worlds. In doing so, it could help bridge the long-standing gap between neural function and behavior.
