‘Dosage sensitivity map’ predicts active ingredients in copy number variants

by  /  31 August 2022

The catalog of rare copy number variants tied to autism and other conditions could help researchers identify which genes account for the mutations’ effects.

Promising preclinical results prompt Angelman therapy trial

by  /  25 August 2022

Roche’s gene therapy drug Rugonersen boosts expression of the protein missing in the syndrome in mice and monkeys, but whether it works in people remains to be seen.

Chromosome 22 mutations leave telltale marks on brain development in autistic people

by  /  24 August 2022

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

‘Double duty’ autism-linked genes upend conventional characterizations

by  /  23 August 2022

What these genes do and how they affect autism depends on when in development they’re studied, despite what classic ‘gene ontology’ analyses say.

Lumping versus splitting with autism-linked variants: A conversation with Vanessa Vogel-Farley and Yssa DeWoody

by  /  22 August 2022

Researchers have long studied subgroups of people who share genetic variants, but the newly formed ‘CNV Commission’ is also looking at people with shared traits across different neurodevelopmental conditions.

Scans of sundry variant types uncover autism-linked genes

by  /  18 August 2022

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.

Mutations disrupting chromatin interactions contribute to autism

by  /  8 August 2022

The mutations occur spontaneously in noncoding stretches of DNA that control gene expression.

Maternal genetics may confound studies of autism’s link to prenatal factors

by  /  2 August 2022

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