    Abstract:
    OBJECTIVE: To determine whether -Taq I T/C and -Fok I C/T polymorphisms of vitamin D receptor (VDR) gene are associated with the familial aggregation of hepatitis B virus (HBV) infection. METHODS: Based on a population-based case-control family design, 288 family members from 27 case families and 230 family members from 27 control families were recruited. VDR gene polymorphisms were analyzed. VDR-Taq I T/C and VDR-Fok I C/T polymorphisms were examined by polymerase chain reaction-restriction fragment length polymorphism. RESULTS: The frequency of VDR-Taq I TT genotype in the case families was significantly higher than that in the control families (P < 0.05) , however, the frequency of VDR-Fok I CC genotype in the case families was significantly higher than that in the control families (P < 0.05). The frequency of family members carriying Taq I T-Fok I C haplotype in the case families was significantly higher than that in the control families (OR = 1.67, P < 0.05), however, the frequency of family members carrying Taq I C-Fok I T haplotype in the case families was significantly lower than that in the control families (OR = 0. 24, P < 0.05). The similar results were found in the familial biological kinship relatives with any HBV-infected makers. CONCLUSION: VDR-Taq I and -Fok I gene polymorphisms are likely to play a substantial role in HBsAg familial aggregation.
