• â Celtic curseâ hotspots found in Scotland and Ireland with 1 in 54 at risk People with roots in the Outer Hebrides and north west Ireland face the highest known risk of developing hemochromatosis, a genetic disorder that causes the body to absorb and store too much iron. • Over time, that excess iron can build up to dangerous levels. • This is the first time researchers have mapped genetic risk for hemochromatosis, sometimes called the ‘Celtic curse’, across the UK and Ireland. • The condition has long been known to affect Scottish and Irish populations at higher rates, but until now its geographic distribution had not been clearly charted. • Experts say the findings could help health officials focus genetic screening in the areas most affected, allowing people at risk to be identified earlier and treated before serious complications develop. • Iron Overload Can Damage Organs Over Decades Hemochromatosis often develops slowly.
Article Summaries:
- Researchers from the University of Edinburgh have mapped the geographic distribution of the hemochromatosis‑risk variant C282Y across the UK and Ireland for the first time. The study, using data from over 400,000 participants in the UK Biobank and Viking Genes projects, identified hotspots in north‑west Ireland and the Outer Hebrides, where roughly 1 in 54 and 1 in 62 people carry the high‑risk allele, respectively. The Outer Hebrides and parts of Scotland also show elevated rates, with about 1 in 117 carriers. These findings could guide targeted genetic screening and early treatment in the most affected regions.
