Genes Involved in Depression Symptomatology Identified in Twin Study

Key clinical point: Depressive symptomatology was associated with DNA methylation of genes involved in stress response, depressive behaviors, and recurrent depression.

Major finding: The researchers identified the cg00554948 probe on chromosome 12 as the most significant finding related to the impact of DNA methylation age on depression.

Study details: The data come from a study of 724 Danish monozygotic twins (362 complete twin pairs; 378 women, 346 men) who were participating in the Middle-Aged Danish Twin Study and the Longitudinal Study of Aging in Danish Twins.

Disclosures: The study was funded by the Danish Council for Independent Research, the European Union’s Seventh Framework Programme, and the Lundbeck Foundation, Denmark. The researchers had no financial conflicts.
