A genome-wide cross-phenotype meta-analysis of the association of blood pressure with migraine.

ABSTRACT: Blood pressure (BP) was inconsistently associated with migraine and the mechanisms of BP-lowering medications in migraine prophylaxis are unknown. Leveraging large-scale summary statistics for migraine (N_cases/N_controls = 59,674/316,078) and BP (N = 757,601), we find positive genetic correlations of migraine with diastolic BP (DBP, r_g = 0.11, P = 3.56 × 10^-06) and systolic BP (SBP, r_g = 0.06, P = 0.01), but not pulse pressure (PP, r_g = -0.01, P = 0.75). Cross-trait meta-analysis reveals 14 shared loci (P ≤ 5 × 10^-08), nine of which replicate (P < 0.05) in the UK Biobank. Five shared loci (ITGB5, SMG6, ADRA2B, ANKDD1B, and KIAA0040) are reinforced in gene-level analysis and highlight potential mechanisms involving
