چکیده انگلیسی
In this work, we discuss clinical and molecular findings on a group of patients in whom a SLC40A1 single copy missense variant was identified. Three novel variants, p.D181N, p.G204R and p.R296Q were functionally characterized. Fpn D181N and R296Q mutants can be classified as full or partial loss of function, respectively. Replacement of G204 with arginine appears to cause a more complex defect with impact both on iron export function and hepcidin sensitivity. This finding confirms the difficulty of predicting the effect of a mutation on the molecular properties of Fpn in order to provide an exhaustive explanation to the wide variability of the phenotype in type 4 hereditary hemochromatosis.
