This study will be completed by determining whether homozygote trait for H63D and associated risk factors (beta thalassémia) can lead to iron overload in Tunisia.
Our study shows that H63D is prevalent and C282Y is rare in north Indians and the presence of 63D mutation does not increase body iron as measured by serum ferritin in beta thalassemia traits.
beta-thalassemia carriers who are homozygotes for the H63D mutation have higher ferritin levels than beta-thalassemia carriers with the H/H genotype, suggesting that the H63D mutation may have a modulating effect on iron absorption.
