These mutations are not found in the common forms of migraine with or without aura. The alpha 1E subunit (Cav 2.3) is the counterpart of Cav 2.1 in R-type Ca2+ channels, has different functional properties, and is encoded by the CACNA1E gene.MethodsFirst, we performed a total exon sequencing of the CACNA1E gene in three probands selected because they had no abnormalities in the three FHM genes. In a patient suffering from basilar-type migraine, we identified a single nucleotide polymorphism (SNP) in exon 20 of the CACNA1E gene (Asp859Glu - rs35737760; Minor Allele Frequency 0.2241) hitherto not studied in migraine. In a second step, we determined its occurrence in four groups by direct sequencing on blood genomic DNA: migraine patients without aura (N = 24), with typical aura (N = 55), complex neurological auras (N = 19; hemiplegic aura: N = 15; brain stem aura: N = 4), and healthy controls (N = 102).ResultsThe Asp859Glu - rs35737760 SNP of the CACNA1E gene was present in 12.7% of control subjects and in 20.4% of the total migraine group. In the migraine group it was significantly over-represented in patients with complex neurological auras (42.1%), OR 4.98 (95% CI: 1.69-14.67, uncorrected P = .005, Bonferroni P = .030, 2-tailed Fisher's exact test). There was no significant difference between migraine with typical aura (10.9%) and controls.ConclusionsWe identified a polymorphism in exon 20 of the CACNA1E gene (Asp859Glu - rs35737760) that is more prevalent in hemiplegic and brain stem aura migraine. This missense variant causes a change from aspartate to glutamate at position 859 of the Cav 2.3 protein and might modulate the function of R-type Ca2+ channels. It could thus be relevant for migraine with complex neurological aura, although this remains to be proven."xsd:string |
