We saw that a study on the association between the HLA alleles of 132 NPC patients in northern China found that HLA-DRB1 alleles with high frequencies of occurrence were -DRB1*09 (35.6%), -DRB1*04 (25.8%), -DRB1*15 (20.5%), -DRB1*07 (22.7%), -DRB1*08 (19,7%), -DRB1*12 (15.9%), and -DRB1*14 (13.6%) (Wang and Wang, 2014) [12]. Here, HLA-DRB1 is linked to nasopharyngeal carcinoma.
