A 2026 whole-genome sequencing preprint found rare variant signals in 2 multiplex obsessive-compulsive disorder (OCD) families: an NPY5R missense variant in 10 of 15 affected people in 1 pedigree, plus DLGAP1 and MAPK8IP3 signals that tracked all 3 sequenced cases in a branch of a second pedigree.1 The finding is a candidate-gene result, not a …
Suicide remains a leading cause of death worldwide, with its prevention a top priority for both public health initiatives and individual care strategies. Recent research in the US Army offers new insights into the genetic underpinnings of suicide attempts, suggesting that polygenic risk scores (PRS) could become a valuable tool in identifying individuals at risk. …
In a study utilizing data from the TOMMORROW trial, researchers have embarked on a novel exploration of genetic associations with cognitive change in older individuals. Employing a genome-wide association study (GWAS) approach, they’ve identified specific genetic variants linked to cognitive dynamics, providing new insights into the genetic underpinnings of cognitive change with aging. Highlights: Novel …
