170 million people worldwide are chronically infected with hepatitis C virus (HCV), which is the leading cause of cirrhosis in North America. Many patients are not cured by the current recommended treatment regime, with patients of European ancestry having a higher probability of being cured than those of African ancestry. Here, a genetic polymorphism near the IL28B gene is found to be associated with a better response to treatment; it occurs with higher frequency in European populations.
