Roughly 90% of haemochromatosis phenotypes occur in people of white European ancestry who are homozygous for the p.Cys282Tyr mutation of HFE, a gene that encodes HFE protein, which modifies iron absorption. Since the discovery of HFE in 1996, the numbers of WebThe c.845G>A (p.Cys282Tyr) missense variant is widely recognized as one of the two most common disease-causing variants in the HFE gene. Cys282Tyr homozygotes account for 80-85% of typical patients with Hereditary Hemochromatosis (HH).
WebDec 1, 1997 · One assumes there are other responsible mutations, either in HFE or elsewhere, but one study from Australia showed that all hereditary HLA linked HHC is due to the Cys282Tyr mutation.4.
