Another CHD SNP enriched in the hepatitis C and hepatocellular carcinoma pathway is rs11838776*A (COL4A2: type IV collagen α2 chain), which is associated with 1.03 times (95% CI: 1.02–1.04) higher CHD risk in our meta-analysis (Tables S2 and S4). This evidence concerns the gene COL4A2 and hepatocellular carcinoma.
