HLA-G and nasopharyngeal carcinoma: Ghandri N et al. [24] examined HLA-G gene polymorphisms in NPC for the first time using the restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR) and the amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) method in Tunisian and found three nonsynonymous SNPs in codons not to associate with NPC susceptibility but implicate in NPC progression and survival.
