title: Putative hemochromatosis gene mutations and alcoholic liver disease with iron overload in Japan.
abstract: It is well known that alcoholic liver disease is associated with iron overload. To study the role of hemochromatosis gene mutations on the pathogenesis of alcoholic liver disease (ALD), we have analyzed C282Y and H63D mutations on the chromosomes obtained from 95 Japanese alcoholics. Patients were divided in two groups [i.e., 64 alcoholic patients with liver damage (group I) and 31 alcoholics without liver damage (group II)]. In group I, biochemical examinations showed that serum levels of iron and ferritin were significantly high, and unsaturated iron binding capacity levels were low, compared with those of group II. An analysis by means of allele-specific polymerase chain reaction demonstrated that C282Y mutation was not observed in both groups I and II. H63D mutation was observed in only two heterozygotes of group I and in one heterozygote of group II. Results could not indicate the relationship between ALD and these mutations. We speculate that other causes of iron overload may exist in ALD with iron overload.
