For a phenotypic description and discussion of genetic heterogeneity of migraine headaches, see MGR1 (157300).
Cader et al. (2003) undertook a genomewide screen of 43 Canadian families, segregating migraine with aura with families chosen for an apparent autosomal dominant pattern of transmission. Parametric linkage analysis revealed a novel locus on 11q24 with a 2-point lod score of 4.2 at marker GATA64D03 (GenBank G08882) and a multipoint parametric lod score of 5.6 with a peak at the same marker. Several candidate ion channel genes map to this region, including GRIK4 (600282), KCNJ5 (600734), and KCNJ1 (600359).
