Chris Spencer, Eleanor Barnes and colleagues use human genotyping arrays and whole-genome viral sequencing to perform a systematic genome-to-genome study of 542 individuals chronically infected with hepatitis C virus (HCV). They show that both HLA alleles and genes encoding factors of the innate immune system drive viral genome polymorphism and that IFNL4 genotypes determine HCV viral load through a mechanism dependent on a specific polymorphism encoded in the HCV polyprotein.
