EGFLAM and xerostomia: Our GWAS identified eight SNPs suggestively associated with higher risk of moderate to severe xerostomia in six genomic regions (2p13.3, rs6546481, Minor Allele (MA) = A, ANTXR1, P = 4.3 × 10–7; 5p13.2–p13.1, rs16903936, MA = G, EGFLAM, P = 5.1 × 10–6; 4q21.1, rs10518156, MA = G, SHROOM3, P = 7.1 × 10–6; 19q13.42, rs11882068, MA = G, NLRP9, P = 1.7 × 10–5; 12q24.33, rs4760542, MA = G, GLT1D1, P = 1.8 × 10–5; and 3q27.3, rs11714564, MA = G, RTP1, P = 2.9 × 10–5.
