NAXD and major depressive disorder: We pinpointed 17 eQTL SNPs in or near 17 loci which possess potential eQTL mechanisms, as well as associations with probable MDD, where the 17 loci are LINC00624-BCL9, TOMM40L (or MIR5187), NR1I3, CEP350-QSOX1, LOC105377123, CTNND2-RNU6-679P, FBN2, MCUR1, BIN3, RPH3A, CYCSP33-PARP4, RAB20-NAXD, PWRN1, METRN, LOC101928474, EEF1A1P7-LINC01531, and PTGIR. It has been indicated that integrating regulatory information (such as eQTLs) enhances the power to identify functional SNPs that may play a key role in the etiology of the disease [16].
