Migraines Stay in the Family through Common Genetic Variants

Migraines often run in families, and although studies have implicated three particular genes in more severe, but uncommon, familial and sporadic forms of migraine, the genetic basis for the most types of migraine that run in families isn’t understood. Scientists in Finland and the U.S now report on an analysis of data from more than 1500 migraine-suffering families, which suggests that an accumulation of many common gene variants, each of which wouldn’t on its own have a major effect
