mtDNA A3243G MELAS mutation is not associated with multigenerational female migraine

The authors searched for mitochondrial DNA (mtDNA) A3243G mutation in peripheral blood leukocytes from female migraine patients with pure matrilinear history of migraine along two or three generations. The current study was designed to exclude any male transmission of the disease. The mutation was absent in all patients. We conclude that mtDNA A3243G mutation does not contribute to the pathogenesis of pure matrilinear multigenerational migraine with or without aura.
