Deleting a copy of the gene TBX1 depletes the fatty myelin insulation that surrounds neurons and reduces cognitive speed in mice.

Genes that appear to play a role in some birds’ ability to learn songs are frequently mutated in autistic people.

Rare variants that alter the expression of genes in the brain contribute to autism in people who also have a rare autism-linked mutation, according to a new study.

Two new methods make it possible to delete long sections of the genome, expanding the reach of CRISPR gene editing.

A MECP2 gene therapy for Rett syndrome eases repetitive behaviors, anxiety and hyperactivity in a mouse model of Pitt-Hopkins syndrome.

These short reports from Spectrum journalists highlight some of the autism-related findings that caught our attention at the meeting this past week.

Treatments that counteract the effects of an SCN2A mutation in mice increase the animals’ sociability in adulthood, according to a new unpublished study.

Dysfunctional circuits and a rogue sodium channel in the brainstem may explain the disordered breathing pattern seen in children with Pitt-Hopkins syndrome, a form of autism.

Compared with a previous mouse strain, a new model better reflects some of the difficulties that people with a rare autism-related syndrome experience, and may help identify biomarkers of the syndrome.

A quarter of autistic people carry rare genetic variations linked to autism and other neurodevelopmental conditions, but these mutations alone may not be enough to lead to autism.
