Circadian Rhythms and Mood Disorders Genetically Linked

A research team at the University of Glasgow has now identified a potential genetic link between disrupted circadian rhythms and mood disorders, including major depressive disorder (MDD) and neuroticism.

The genome-wide association study (GWAS), involving data on more than 70,000 individuals in the U.K. Biobank, identified two gene regions that appear to be linked with disruption to rest-activity cycles.

One of these contains a gene that interacts with a protein implicated in bipolar disorder (BD).
