It appears unlikely that the common ESR1 variants rs2234693 and rs9340799 are associated with moderate depressive symptoms in women; however, there is some evidence that indicates a significant association with more severe depressive symptoms, major depressive disorder and anxiety.
Women homozygous for the variant G allele of ESR1 rs9340799 had a 1.6-fold increased risk of MDD across their lifetime compared with women who were homozygous for the A allele (p=0.009).
