Rare Iron Overlaods Clinical Trial
Official title:
Hepcicor Cohort : Clinical, Biological, Genetic and Fonctional charactérization of Rare Iron Overlaod phénotypes Associated With Hepcidin Deficiency Excluding C282Y Homozygosity
The study explores the hepcidin deficiency causes of rare iron overload (excluding C282Y homozygosity), and aim to characterize this iron overload in term of clinical, biological, genetic and functional spacificities.
Chronic iron overload are responsible for morbidity and mortality. There are many causes, genetic and acquired. Hepcidin deficiency related to genetic desease is one of them. This study concerns specifically this cause, and seeks to characterize these iron overloads on clinical, biological, genetic and functional point of view. A significant number of patients with chronic iron overload, present a phenotype of hepcidin deficiency. This profile is characterized by an elevated plasma iron increased serum transferrin saturation, a transferrin saturation, and a parenchyma distribution of iron overload. These diseases either remains unexplained or are associated with mutations in the gene involved in iron metablism regulation. The main objective of this study is to characterize these iron overloads with phenotype of hepcidin deficiency not related to homozygosity C282Y (clinical, biological and genetic). ;
