HLA-G and hepatocellular carcinoma: For example, the study conducted by Teixeira et al. [41] demonstrated that individuals with the HLA-G 14-bp Ins/Del polymorphism had significantly increased risk for the occurrence of HCC, while Kim et al. [47] showed no relationship between the HLA-G 14-bp Ins/Del variant and HCC susceptibility; however, Jiang et al. [13] indicated that this variation may actually be a protective factor in HCC susceptibility.
