In another study in Tunisia (north Africa) on 25 NPC patients, there were 23 identified HLA-B alleles, and those with the highest frequencies were HLA-B*50 (32%), -B*51 (32%), -B*44 (20%), -B*08 (16%), -B*27 (16%), and -B*52 (16%) (Nehla et al., 2017) [21]. The gene discussed is HLA-B; the disease is nasopharyngeal carcinoma.
