GABBR1 and nasopharyngeal carcinoma: In the previous GWAS study on NPC, a total of 15 SNPs in the HLA region were reported.12, 13, 14, 15 In this study, we replicated three SNPs in GABBR1, two SNPs in HLA‐A, two SNPs in HCG and one SNP in HLA‐B/C with association significance at GWAS level (P < 5 × 10−8).
