We found that rs2856718 and rs9275572 in HLA-DQ significantly decreased HBV-related HCC in total population, especially in Chinese, but not in Saudi Arabian.
Several recent genome-wide studies showed that the genetic polymorphisms in the HLA-DQ region (rs9275572 and rs2856718) were related to chronic hepatitis B virus (HBV) infection and chronic hepatitis C virus (HCV)-associated hepatocellular carcinoma (HCC).
Two recent genome-wide studies showed that the single-nucleotide polymorphisms in the HLA-DQ region (rs2856718 and rs9275572) were associated with chronic hepatitis B virus infection and chronic hepatitis C virus-associated hepatocellular carcinoma in Japanese patients.
Logistic regression analyses showed that HLA-DQ rs2856718 significantly decreased host HCC risk, whereas three SNPs were associated with HBV clearance (HLA-DP rs9277535 as well as HLA-DQ rs7453920 and rs2856718).
