Six single nucleotide polymorphisms (SNPs) of the KCNK2 gene were investigated for their association with major depressive disorder (MDD) and treatment efficacy in 590 MDD patients and 441 controls. The A homozygotes of rs10779646 were significantly more frequent in patients than controls whereas G allele of rs7549184 was associated with the presence of psychotic symptoms and the severity of disease. Evaluating the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) dataset, we confirmed our findings.
