BACKGROUND & AIMS Mutations in the hemochromatosis gene (HFE) (C282Y and H63D) lead to parenchymal iron accumulation, hemochromatosis, and liver damage. We investigated whether these factors also contribute to the progression of fibrosis in patients with nonalcoholic fatty liver disease (NAFLD). METHODS We studied clinical, histologic (liver biopsy samples for hepatocellular iron accumulation...
BACKGROUND AND OBJECTIVE Most patients with hereditary hemochromatosis are homozygous for a Cys282AETyr mutation in the HFE gene. This mutation has been shown to impair the association of the HFE gene product with b(2)-microglobulin and to prevent its cell surface presentation in transfected COS-7 and 293 cells. This study was performed to examine the expression of HFE protein in epithelial cel...
Genetic haemochromatosis (HFE) is a frequent and potentially fatal disease. Early phlebotomies may prevent complications. The recessive gene for HFE is unknown but closely linked to the HLA-A locus. No direct test for homozygosity for HFE is currently available, apart from HLA typing within the family of a patient with confirmed HFE. During a reverse genetic approach to identify the gene, we fo...
Because body iron burden is inversely associated with lead absorption, genes associated with hemochromatosis may modify body lead burden. Our objective was to determine whether the C282Y and/or H63D hemochromatosis gene (HFE) is associated with body lead burden. Patella and tibia lead levels were measured by K X-ray fluorescence in subjects from the Normative Aging Study. DNA samples were genot...
BACKGROUND Hereditary hemochromatosis (HH) is the most common autosomal recessive disorder in white people, characterized by highly abnormal uptake of iron from the gastrointestinal tracts. Recently, mutation studies have focused to detect the genes responsible for HH. MATERIAL/METHODS In this cross-sectional study, 12 HH patients were recruited, who were referred to Firoozgar Hospital, Tehra...
OBJECTIVES To determine the value of screening patients with inflammatory arthritis for haemochromatosis-associated mutations in the HFE gene. METHODS We screened 1000 patients with inflammatory arthritis and 1000 controls for the HFE gene mutations that are associated with haemochromatosis. The arthritis patients were diagnosed between 1989 and 1995 and their blood DNA was archived as part o...
Iron is an essential trace element whose absorption is usually tightly regulated in the duodenum. HFE-related hereditary hemochromatosis (HH) is characterized by abnormally low expression of the iron-regulatory hormone, hepcidin, which results in increased iron absorption. The liver is crucial for iron homeostasis as it is the main production site of hepcidin. The aim of this study was to explo...
The pathogenesis of diabetes associated with hemochromatosis is not known. We therefore examined glucose homeostasis and beta-cell function in mouse models of hemochromatosis. Mice with targeted deletion of the hemochromatosis gene (Hfe(-/-)) on the 129/Sv genetic background exhibited a 72% increase in iron content in the islets of Langerhans compared with wild-type controls. Insulin content wa...
