A genome-wide analysis of pleiotropic associations shared between endometriosis and psychiatric disorders identified 1 locus, DGKB rs12666606, with evidence of pleiotropy between endometriosis and depression after multiple testing correction (z = −9.46 for endometriosis, z = 8.10 for depression, P = 5.56 × 10−8; false discovery rate q = 4.95 × 10−4). The gene discussed is DGKB; the disease is endometriosis.
