Abstract

Donor genotype for polymorphisms near IFNL3 influences hepatitis C virus (HCV) therapy responsiveness. This relationship has not been studied in a sample of HCV-infected living donor liver transplantation (LDLT) recipients in the United States (US). We investigated the association of donor and recipient genotypes near the IFNL3 gene at a large US liver transplant center. Recipient homozygosity for rs12979860 C was associated with increased sustained virologic response (SVR) in antiviral treatment-experienced patients pretransplant (P = 0.055). Consistently, donor homozygosity for rs12979860 C was also associated with increased SVR in patients who received post-transplant antiviral therapy (P = 0.048). Transplantation of an rs12979860 CC graft confers a favorable post-transplant antiviral response among HCV-positive recipients in an LDLT setting. Recipients with the favorable rs12979860 genotype receiving antiviral therapy before transplant are also more likely to achieve SVR. The effect of genotype status in the era of direct-acting antiviral agents will require future study.
