A more recent case study featuring a male adolescent who was diagnosed with familial hemiplegic migraine (FHM2) revealed a heterozygous genetic mutation within the ATP1A2 gene (c.1133C > T); this missense mutation may inhibit the function of the α2 subunit of the Na+/K+ ATPase [206]. Here, ATP1A2 is linked to familial hemiplegic migraine.
