MICU1 and migraine disorder: The study by Menon and collaborators [43] has investigated in an Australian population the role of the polymorphism rs35815751, consisting in a 16 bp deletion in the first intron of the CALC A gene that is a region with triplet G-run motifs, in the development of migraine with aura: no significant association between rs35815751 and migraine [for genotypes (P = 0.575) nor alleles (P = 0.502)], and migraine with aura (genotypes, P = 0.666; alleles, P = 0.7) or without aura (genotypes, P = 0.325; alleles, P = 0.276) has been found.
