Type 4B hereditary hemochromatosis associated with a novel mutation in the SLC40A1 gene
RATIONALE Hereditary hemochromatosis can be divided into HFE- and non-HFE-related based on genetic mutations in different genes. HFE-related hemochromatosis is the most common inherited genetic disease in European populations but rare in Asia-pacific region. Recently, non-HFE-related hemochromatosis has been reported in patients from the Asian countries. PATIENT CONCERNS We report the case of...
متن کاملNon-HFE hemochromatosis: pathophysiological and diagnostic aspects.
Rare genetic iron overload diseases are an evolving field due to major advances in genetics and molecular biology. Genetic iron overload has long been confined to the classical type 1 hemochromatosis related to the HFE C282Y mutation. Breakthroughs in the understanding of iron metabolism biology and molecular mechanisms led to the discovery of new genes and subsequently, new types of hemochroma...
متن کاملIron-overload-related disease in HFE hereditary hemochromatosis.
BACKGROUND Most persons who are homozygous for C282Y, the HFE allele most commonly asssociated with hereditary hemochromatosis, have elevated levels of serum ferritin and transferrin saturation. Diseases related to iron overload develop in some C282Y homozygotes, but the extent of the risk is controversial. METHODS We assessed HFE mutations in 31,192 persons of northern European descent betwe...
متن کاملCoinheritance of hereditary spherocytosis and reversibility of cirrhosis in a young female patient with hereditary hemochromatosis
Here we report a 33-years-old woman with hereditary spherocytosis and hemochromatosis due to homozygosity for the C282Y mutation of the HFE gene. The coinheritance of both conditions led to severe iron overload and liver cirrhosis at young age. The patient was treated by repeated phlebotomy, and reversibility of cirrhosis was documented by transient elastography. This report discusses the patho...
متن کاملMolecular basis of HFE-hemochromatosis
Iron-overload disorders owing to genetic misregulation of iron acquisition are referred to as hereditary hemochromatosis (HH). The most prevalent genetic iron overload disorder in Caucasians is caused by mutations in the HFE gene, an atypical MHC class I molecule. Recent studies classified HFE/Hfe-HH as a liver disease with the primarily failure in the production of the liver iron hormone hepci...
متن کاملIron Overload and Diabetes Risk: A Shift From Glucose to Fatty Acid Oxidation and Increased Hepatic Glucose Production in a Mouse Model of Hereditary Hemochromatosis
OBJECTIVE Excess tissue iron levels are a risk factor for diabetes, but the mechanisms underlying the association are incompletely understood. We previously published that mice and humans with a form of hereditary iron overload, hemochromatosis, exhibit loss of β-cell mass. This effect by itself is not sufficient, however, to fully explain the diabetes risk phenotype associated with all forms o...
