were shown to affect clearance of hepatitis C virus (HCV) infection in genome-wide association (GWA) studies. Only a fraction of patients with chronic HCV infection develop liver fibrosis, a process that might also be affected by genetic factors. We carried out a 2-stage GWA study of liver fibrosis progression related to HCV infection.</p>
</sec>
<sec id="S2">
<title>METHODS</title>
<p id="P3">We studied well-characterized HCV-infected patients of European descent who had liver biopsies before treatment. We defined various liver fibrosis phenotypes on the basis of Metavir scores, with and without taking the duration of HCV infection into account. Our GWA analyses were conducted on a filtered primary cohort of 1161 patients using 780,650 single nucleotide polymorphisms (SNPs). We genotyped 96 SNPs with
