Phenotypic and functional data confirm causality of the recently identified hemojuvelin p.r176c missense mutation.

Abstract excerpt

In the present study, we correlate homozygosity for the very recently identified HJV p.R176C substitution with a juvenile hemochromatosis phenotype. We also show that the p.R176C variant fails to up-regulate the hepcidin promoter activity. Altogether, our results definitively show the R176C amino-acid change to be a novel hemojuvelin loss-of-function mutation.
