Abstract
Twin and family studies provide evidence of a genetic component in migraine, in particular migraine with aura (MA). Familial hemiplegic migraine (FHM) is a rare monogenic subtype of MA for which three causative genes have been identified: CACNA1A (FHM1), ATP1A2 (FHM2), and SCN1A (FHM3). Mutations in these genes are also found in some patients with sporadic hemiplegic migraine. Linkage studies have identified several gene loci for the more common forms of migraine; however, identification of the respective causative genes is still pending. This review summarizes recent developments in the genetics of migraine and their implications for molecular genetic testing. We further discuss the roles of CACNA1A, ATP1A2, and SCN1A in the pathophysiology of cortical spreading depression, which is the likely correlate of migraine aura.
