Utilizing genome-wide association studies (GWASs) to examine the variation in hepatitis
C virus (HCV) phenotypes has led to quantum improvements in our understanding of both
the genetic basis and the underlying pathogenesis of HCV infection. In this context,
the discovery of interferon lambda polymorphisms is unique with far reaching implications
that extend well beyond HCV to various other liver and extrahepatic diseases. In this
review, we summarize the data on the impact of GWASs on our understanding of HCV disease.
