Identification of novel OCT4 genetic variant associated with the risk of chronic hepatitis B in a Korean population

摘要

Background Aims Hepatitis B viral infection is a serious risk factor for chronic hepatitis B (CHB), cirrhosis and hepatocellular carcinoma. Recently, several genome-wide association studies (GWASs) have been conducted to identify important genetic variant associated with the risk of CHB. In our previous GWAS,TCF19 was identified as one of the susceptibility genes for CHB risk (P=4.2x10(-9) at rs1419881). In order to discover possible additional causal variants around TCF19, we performed an association study by genotyping single nucleotide polymorphisms (SNPs) in OCT4, a nearby gene to TCF19.
