BackgroundThe human HFE gene (a key component of iron homeostasis in humans) is involved in hereditary hemochromatosis, a common autosomal recessive genetic disorder that is characterized by excessive intestinal iron absorption and progressive iron overload.ObjectivesIn this study, we assessed the frequency of two common forms of hemochromatosis HFE gene mutation (C282Y and H63D) in patients suffering from cryptogenic cirrhosis.Patients and MethodsOne hundred and fifty individuals were included in this study, in which 100 were patients with cryptogenic cirrhosis and 50 were from the normal population. All individuals were examined for common HFE gene mutations by amplification of nucleotide 845 C282Y and 187 H63D alleles and product analysis using the polymerase chain reaction method and restriction enzyme digestion.ResultsNo case of either a homozygous or heterozygous C282Y mutation was found. For the H63D mutation, no homozygosity was detected but heterozygosity was detected in 22% of patients and in 28% of the normal population.ConclusionsHereditary hemochromatosis is not a major cause of cryptogenic cirrhosis in the Iranian population.
