Notes

rs11172113 is a SNP on ch 12q13.3 in the LRP1 gene. A large GWAS study of over 5,000 patients with migraines and a meta-analysis concluded that this SNP was one of three influencing the condition, albeit with only slight risk changes on its own. The odds ratio for the less common rs11172113(C) allele was 0.9 (CI: 0.87 - 0.93, p = 4.3 x 10e-9).
