Abstract

Hepatitis C virus (HCV) infection results in chronic hepatitis in more than 80% of infected patients while 10-20% of patients recover spontaneously. Host genetic factors may influence the ability to clear the virus after infection. Six single nucleotide polymorphisms and a 32 bp deletion in the genes coding for CCR3, CCR2 and CCR5 (which are all located in a cluster on chromosome 3) were investigated in 465 consecutively recruited patients infected with HCV and 370 matched controls. Genetic variants were tested for association with spontaneous viral elimination and, in the chronically infected patients, stage of fibrosis and response to antiviral therapy. The G190A polymorphism (variant allele Ile64) in the first transmembrane domain of CCR2 was under-represented in the 29 patients who had cleared the hepatitis C virus spontaneously (P = 0.018). None of the other variants in the CCR gene cluster showed association with the natural course of the infection, stage of fibrosis or response to therapy.
