Notably, results from the Taiwan NPC GWAS (10) suggested significant associations for the HLA complex group 9 (HCG9) gene (rs9260734, PGWAS = 2.49 × 10−7, Pcombined = 6.77 × 10−18, OR = 1.85), and the gamma-aminobutyric acid (GABA) B receptor 1 (GABBR1) gene (rs29232, PGWAS = 1.67 × 10−8Pcombined = 8.97 × 10−17, OR = 1.67). Here, HCG9 is linked to nasopharyngeal carcinoma.
