SNP, single nucleotide polymorphism; G, genotype; F, frequency both absolute (N) and relative (%); COMT, catechol-O-methyl transferase. P-value obtained from the χ2-test of Hardy Weinberg equilibrium.
a[wildtype (wt)/variant (v)]; bExact test for Hardy-Weinberg equilibrium; cχ2-test for genotype distribution, non-hepatitis C patients vs hepatitis C patients; MAF: Minor allele frequency.
