Genetic variants of the NOTCH3 gene in migraine--a mutation analysis and association study.
Mutations in the NOTCH3 gene cause cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Exons 3 and 4 are mutation hotspots. Migraine is a clinical hallmark of CADASIL. The objective of this study was to investigate whether genetic variants in exons 3 and 4 of the NOTCH3 gene are associated with migraine. Exons 3 and 4 of the NOTCH3 were analysed for mutations and polymorphisms by direct DNA sequencing in 97 migraineurs and the same number of control individuals. No mutations in exons 3 and 4 of the NOTCH3 gene were found in 97 patients with migraine. However, association analysis revealed significant association of the single nucleotide polymorphism (SNP) rs1043994 with migraine.
