We examined cardiovascular disease risk factors and iron and liver biomarkers, as well as morbidity and mortality associated with the C282Y and H63D variants of HFE in the Atherosclerosis Risk in Communities (ARIC) study, which is a population-based cohort of nearly 16,000 U.S. white and black men and women who were 45-64 years old at baseline.
The finding of a similar prevalence of Cys282Tyr and His63Asp mutations in the HFE gene among controls and patients with coronary atherothrombotic disease, indirectly questions the possibility of an association between hereditary hemochromatosis and atherosclerosis.
To test whether genetic haemochromatosis is associated with increased atherosclerosis, we determined the prevalence of two mutations in the HFE gene related to haemochromatosis (845G-->A; Cys282Tyr. and 187 C-->G, His63Asp) in 265 consecutive patients with premature (<50 years of age) angiographically-proven atherosclerotic disease (coronary and/or peripheral), and in 272 healthy controls.
