EPHB4 and hemorrhage: Five SNPs in two angiogenic genes were discovered to contribute to bAVM-related hemorrhage: VEGFA rs1547651 (OR, 2.11; 95% CI, 1.01–4.42) in dominant models, and rs314346 (OR, 1.67; 95% CI, 1.04–2.68), rs314353 (OR, 1.79; 95% CI, 1.11–2.89), rs314308 (OR, 0.36; 95% CI, 0.20–0.65), and rs314313 (OR, 0.45; 95% CI 0.25–0.79) in allelic models of EPHB4.
