A genome-wide association study on chronic HBV infection and its clinical progression in male Han-Taiwanese.

ABSTRACT: It is common to observe the clustering of chronic hepatitis B surface antigen (HBsAg) carriers in families. Intra-familial transmission of hepatitis B virus (HBV) could be the reason for the familial clustering of HBsAg carriers. Additionally, genetic and gender factors have been reported to be involved. We conducted a three-stage genome-wide association study to identify genetic factors associated with chronic HBV susceptibility. A total of 1,065 male controls and 1,623 male HBsAg carriers were included. The whole-genome genotyping was done on Illumina HumanHap550 beadchips in 304 healthy controls and HumanHap610 beadchips in 321 cases. We found that rs9277535 (HLA-DPB1, P = 4.87×10(-14)), rs9276370 (HLA-DQA2, P = 1.9×10(-12)), rs7756516 and rs7453920 (HLA-DQB2, P = 1.48×10(-11) and P = 6
