What molecular mechanisms explain the heterosis effect of KCNK2 rs6686529 in MDD susceptibility?

OPEN

The study found that heterozygous carriers have reduced MDD susceptibility compared to both homozygous genotypes, but the underlying biological mechanism for this heterosis effect remains unexplained. Understanding this could reveal novel protective pathways in depression. Gap type: unexplained_observation Source paper: Support for the involvement of the KCNK2 gene in major depressive disorder and response to antidepressant treatment. (None, None, PMID:19741570)
