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.

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 | Spectrum | Autism Research News

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.

Chromosome 22 mutations leave telltale marks on brain development in autistic people | Spectrum | Autism Research News

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 | Spectrum | Autism Research News

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 | Spectrum | Autism Research News

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.

Deletions on chromosome 22 have ripple effects across genome | Spectrum | Autism Research News

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.
