The association over APOB is 380 kb from a previously reported BE signal30 over the GDF7 gene, which also shows some signal for GERD; the peak SNP (rs3072) near GDF7 has no correlation with rs11901649 (r2 = 0.01), but it has a suggestive level of association with GERD (P = 1.68 × 10−7). Here, GDF7 is linked to gastroesophageal reflux disease.
