An analysis of pooled data from two NPC case-control studies conducted in Taiwan that jointly evaluated HLA-A and GABBR1 reported that while the effect of GABBR1 was attenuated by adjustment for HLA-A alleles, a significant effects for GABBR1 (rs29232) remained after adjustment for HLA-A and that an independent effect of GABBR1 could therefore not be ruled out (20). This evidence concerns the gene GABBR1 and nasopharyngeal carcinoma.
