Deskripsi
Background: Development of cirrhosis and hepatocellular carcinoma (HCC) in patients with high alcohol intake is modulated by genetic predispositions. Genetic variation in angiotensin II type 1 receptor (<i>AGTR1</i>) has been described as a risk factor for non-alcoholic fatty liver disease in Asian patients. Methods: We analysed Caucasian patients with alcohol–associated cirrhosis without (n = 238) and with (n = 339) HCC, healthy controls (n = 200), and HCV–infected cirrhotic patients with and without HCC (n = 263) for association with the polymorphisms rs3772622 and rs2276736 in <i>AGTR1</i>. Results: Rs2276736 in <i>AGTR1</i> was associated with both low–density lipoprotein (LDL) cholesterol levels and hepatic steatosis in patients with alcohol–associated liver disease. The distribution of genotypes for both rs3772622 and rs2276736 in <i>AGTR1</i> were comparable between controls, cirrhosis patients, and those with HCC. Minor allele frequencies were 32% (44%) in healthy controls, 35%/34% (46%/45%) in alcohol–associated liver disease without/with HCC and 31%/38% (43%/39%) in HCV cirrhosis and HCV HCC, respectively. The genotype of the most important genetic risk factor for fatty liver disease, <i>PNPLA3</i> I148M, did not interact with the <i>AGTR1</i> polymorphisms. Conclusion: Genetic variation in <i>AGTR1</i>, although associated with blood lipid levels and hepatic steatosis, is not a risk factor for alcohol–associated cirrhosis or HCC in Caucasians.
