rs11134527 may be a novel genetic risk factor of HCC in HBV-exposed subjects, can facilitate HBV preS deletion generation and predispose the host to the effect of T1674C/G and preS1 start codon mutation in hepatocarcinogenesis.
However, no significant association between the rs11134527 polymorphism and hepatocellular carcinoma risk was observed in all comparison models tested (AG vs AA: OR=0.94, 95%CI: 0.79-1.11; GG vs AA: OR=0.88, 95%CI: 0.70-1.10; GG+AG vs AA: OR=0.92, 95%CI: 0.79-1.08; GG vs AA+AG: OR=0.91, 95%CI: 0.75-1.11).
These findings suggested that the AG genotype of pri-miR-218 rs11134527 might relate to genetic predisposition and be involved in regulating the expression of AFP in Chinese HCC patients.
