Ethnic Differences in Iron Absorption (FeGenes) — FeGenes  

Iron Overload Clinical Trial

Official title:
Ethnic Differences in Iron Absorption

Clinical Trial Summary

This study aims to; 1) investigate population differences in iron absorption between East Asians and Northern Europeans; 2) assess population differences in hormonal and biochemical determinants of Fe absorption between East Asians and Northern Europeans; and 3) to investigate genetic contributions to Fe absorption, Fe status and Fe regulatory hormones between East Asians and Northern Europeans.

Clinical Trial Description

Detailed description: This study will utilize a multidisciplinary approach to identify genetic variation in genes that control iron utilization in order to shed light on the genetic basis of population differences in iron status and disease susceptibility with a long-term goal of informing population-specific dietary iron intake recommendations to minimize the risk of chronic diseases. To evaluate iron utilization, we will employ an in vivo, functional approach using an oral stable iron isotope method. Each participant will have genetic ancestry and genotyping evaluated using the Illumina Global Diversity Array-8. Study participants (n=504, aged 18-50 y) will consume 57Fe (as ferrous sulfate) in the fasted state and will then ingest a standardized breakfast and lunch meal. Two weeks after iron dosing, a blood sample will be collected from each participant and the amount of 57Fe incorporated into red blood cells will be measured using magnetic sector thermal ionization mass spectrometry. This project will fundamentally advance our understanding of ethnic differences in nutrient metabolism and iron status. It will also provide information to assist with the long-term goal of reducing the public health burden of Fe-related diseases. ;
