HFE gene mutations in cryptogenic and HBV related cirrhosis

Le résumé fourni par la source

Background/aims: The liver leads the list among the affected organs in hereditary hemochromatosis. We have limited knowledge about HFE gene mutations in cryptogenic cirrhosis and hepatitis B virus -related cirrhosis, which are the two important sub-titles in liver cirrhosis. We studied HFE gene mutations in these patient groups. Methods: Fiftyeight patients with cirrhosis were included in the study. The patients were divided into two equal groups. Group 1 consisted of patients with cryptogenic cirrhosis and Group 2 of patients with cirrhosis appearing on the base of hepatitis B virus . The following 12 mutations of the HFE gene were studied in both groups: V53M, V59M, H63D, H63H, S65C, Q127H, P160delC, E168Q, E168X, W169X, C282Y, and Q282P. Results: Eighteen patients were female and 40 were male. The average age in the first group was 44.35±20.6 and in the second group was 49.39±12.17; there was no statistically significant difference between the groups (p=0.230). In the cryptogenic cirrhosis patients, the total rate of allelic H63D mutation was found as 24.13% (7/29). C282Y heterozygote mutation was determined in one patient (1/29; 3.44%). In the second group, total allelic mutation rate was 20.68% (6/29). No statistically significant difference was determined between the two groups with respect to mutation rates (p=1.0). The total prevalences of H63D and C282Y mutations were found as 22.4% (13/58) and 1.72% (1/58), respectively. H63D homozygosity was found as 3.44% (2/58) and heterozygosity as 18.96% (11/58). Conclusions: The HFE gene mutation rates in cryptogenic and hepatitis B virus cirrhosis were found to be similar. C282Y mutation has been put forward in this study for the first time in our area.
