Previous research found that variants of the glucocorticoid receptor (GR) (9β, ER22/23EK, BclI, TthIIIl, NR3C1-1 and N363S) and mineralocorticoid receptor (MR) gene polymorphism (-2 C/G and I180V) are associated with both glucocorticoid (GC) sensitivity and major depressive disorder (MDD).
Common functional MR single nucleotide polymorphisms (SNPs; MR -2G/C and I180V) and haplotypes were tested for association with variability in the CAR in a large cohort (Netherlands Study of Depression and Anxiety, NESDA) of patients diagnosed with a lifetime major depressive disorder (MDD).
Interactions with CM were found for several genes; the strongest interactions were found for NR3C2, where the minor allele of SNP rs17581262 was related to smaller hippocampal volume, smaller amygdala volume, higher DST levels, and higher odds of MDD diagnosis only in participants with CM.
