These scores — composite measures of a person’s autism-linked common genetic variants — cannot predict an autism diagnosis but could help researchers better understand the condition’s underlying biology.

Many autism-linked genes are somehow tied to cilia, the tiny hair-like sensors that stud a cell’s surface. But the question remains whether, and how, cilia differences contribute to the condition.

Having an infection during pregnancy is tied to a small increase in the chances of having an autistic child, but the connection may not be causal.

The results highlight the importance of subgrouping study participants based on their underlying genetics, the researchers say.

Intentional interactions with autistic people led Sasson to refocus his research.

Many brain regions develop differently between people with 22q11.2 duplications and deletions, and those trajectories also vary with a person’s diagnosis.

Women who carry genetic variants tied to autism have an elevated chance of experiencing pregnancy-related events linked to the condition in their children.

Deletion of the 22q11.2 chromosomal region alters the expression of numerous autism- and schizophrenia-linked genes, most of which are not contained within the deleted region, a new study suggests.

The catalog could help researchers understand the effects of autism-linked DNA variants that fall outside genes.

Therapies that target the circuit could boost social activity, new findings suggest.
