[Thalassemia minor with iron overload: genetic and clinical study of a family].

A patient with thalassemia minor (TM) is reported who ingested 80 g of alcohol/day and presented an important overload of iron with deposits and a hepatic iron ratio compatible with primary hemochromatosis. The results obtained from the study of histocompatibility antigens, clinical manifestations and family analysis discarded the possibility of two genetic diseases, beta-thalassemia and primary hemochromatosis, being concomitantly present in the same progeny. Thalassemia minor and alcoholic hepatopathy are considered as having acted together and being responsible for the iron overload. The relation between alcohol ingested, TM and iron deposits is discussed.
