For example, using the rSNPBase database [70], we discovered intronic NRXN1 variants associated with expression quantitative trait loci genes such as Rho GTPase activating protein 26 (ARHGAP26), which is differentially expressed in the dorsolateral prefrontal cortex between suicide and non-suicide mood disorder subjects [71]. The gene discussed is NRXN1; the disease is mood disorder.
