In contrast, five polymorphic residues showed significant negative associations: 76M in P4 pockets; 8L and 11G in P6 pockets; 9F in P9 pockets and 57E adjacent to P9 pocket. Quite interestingly, all the residues showing significant positive or negative association

HCV-HCM was associated with
22、DPB1 alleles. The candidate genes may encode molecules involved in the immunity and inflammation.,Shichi D et al Tissue Antigen 2005:66:200,HCM,DCM,HLA and HCV Infection,Our study provides new and suggestive information on the immunological involvement of DPB1 gene in the HCV-HCM development. The po

The existence of different risk alleles among HCV-related diseases including chronic liver disease, asymptomatic carrier and HCV- DCM suggests that
