Partner selection may amplify rare variants in children
Nonrandom mating — the propensity for people to partner with others who share their traits — can increase the likelihood of autism or other conditions across generations.

Mitochondria mediate effects of PTEN mutations
Whole-genome sequencing data — which include information about mitochondrial DNA — offer clues to why mutations in the same gene can lead to autism or cancer.

Brain signatures of rare variants hint at cardiovascular risk
People whose brains look like those of people who carry autism-linked copy number variants also share markers of heart health.

Common and rare autism-linked variants share functional effects
Within the 16p region of the genome, the two types of variants similarly decrease neuronal gene expression — an effect that may reflect their spatial relationship.

Autistic people at increased genetic risk of sleep problems
Compared with their unaffected siblings and unrelated controls, children with autism harbor more copy number variants in genes that govern the circadian cycle or are associated with insomnia.

Autism’s genetic heterogeneity evident in brain connectivity patterns
The results highlight the importance of subgrouping study participants based on their underlying genetics, the researchers say.

‘Dosage sensitivity map’ predicts active ingredients in copy number variants
The catalog of rare copy number variants tied to autism and other conditions could help researchers identify which genes account for the mutations’ effects.

Chromosome 22 mutations leave telltale marks on brain development in autistic people
Many brain regions develop differently between people with 22q11.2 duplications and deletions, and those trajectories also vary with a person’s diagnosis.

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

The visual system’s lingering mystery: Connecting neural activity and perception
Figuring out how the brain uses information from visual neurons may require new tools. I asked 10 neuroscientists what experimental and conceptual methods they think we’re missing.
