Abstract

BACKGROUND & AIMS: Hereditary iron overload associated with mutations in the ferroportin gene produces a dichotomy of phenotypes resulting from either increase or decrease in iron efflux capacity. In this study, we examined the molecular basis of iron overload in a family of Vietnamese origin, characterized the molecular and cellular defect, and correlated it with the clinical and pathological phenotype. METHODS: We analyzed the ferroportin gene by DNA sequencing. The molecular characterization was performed by immunofluorescence microscopy analysis of transfected cells. We analyzed ferritin levels, in cells expressing wild-type and mutant ferroportin, to define the nature of the molecular d..
