Comparison of functional variants in IFNL4 and IFNL3 for association with HCV clearance. J Hepatol 2015 Nov;63(5):1103-10. Epub 2015 Jul 15.
Abstract
Genetic polymorphisms within the interferon lambda (IFN-λ) region are strongly associated with hepatitis C virus (HCV) clearance; the IFNL4-ΔG/TT (rs368234815) polymorphism, which controls the generation of IFN-λ4 protein, is more strongly associated with HCV clearance than rs12979860 (the 'IL28B variant'). An IFNL3 3' untranslated region polymorphism (rs4803217) has been proposed as a causal variant that may affect HCV clearance by altering IFNL3 mRNA stability.
