No association of migraine to the GABA-A receptor complex on chromosome 15.
To date, no gene variants predisposing to common forms of migraine have been convincingly identified. Recently, significant linkage to a cluster of gamma-amino butyric acid (GABA)-A receptors on Chr 15q11-q13 was reported. We performed an extensive association study using 898 MA cases and 900 matched controls by covering the same gene cluster with 34 single nucleotide polymorphisms (SNPs). No association to MA was detected, suggesting that common variants of the GABA cluster are unlikely to be major contributors of MA susceptibility.
