Migraine is a common complex disorder that shows strong familial
aggregation. There is a general increased prevalence of migraine in females
compared with males, with recent studies indicating that migraine affects
18% of females compared with 6% of males. This preponderance of females
among migraine sufferers coupled with evidence of an increased risk of
migraine in first degree relatives of male probands but not in relatives of
female probands suggests the possibility of an X-linked dominant gene. We
report here the localization of a typical migraine susceptibility locus to
the X chromosome. Of three large multigenerational migraine pedigrees two
families showed significant excess allele sharing to Xq markers (P = 0.031
and P = 0.012). Overall analysis of data from all three pedigrees gave
significant evidence in support of linkage and heterogeneity (HLOD = 3.1).
These findings provide conclusive evidence that familial typical migraine
is a heterogeneous disorder. We suggest that the localization of a migraine
susceptibility locus to the X chromosome could in part explain the
increased risk of migraine in relatives of male probands and may be
involved in the increased female prevalence of this disorder.
