More unexpectedly, many genes that contribute to migraine susceptibility are involved in metal ion homeostasis according to Gene Ontology (GO) terms (PRDM16, TGFBR2, REST, FHL5, NRP1, MMPED2, LRP1, ZCCHC14, RNF213, JAG1, SLC24A3) suggesting the importance of these pathways in migraine pathophysiology [162]. The gene discussed is SLC24A3; the disease is migraine disorder.
