Fig. 3From: Genetic studies of Polish migraine patients: screening for causative mutations in four migraine-associated genesA1067T mutation in SCN1A. Exon 16 with flanking intronic regions of SCN1A gene was analyzed as described in the “Materials and methods” section. The missense variant at chr2:166892788, g.37362G>A, c.3199G>A, rs2298771 resulting in amino acid change A1067T found in 12 patients with different phenotypes (20 % of the study group) and present at the high frequency of 24 % in dbSNP database is indicated by frameBack to article page
