Imagine a hidden health risk, lurking in your genes, potentially damaging your organs without you even knowing. That's the reality for thousands in Northern Ireland who may be affected by haemochromatosis, often called the 'Celtic Curse.' But here’s the good news: free testing is now being offered to help identify those at risk and prevent serious health complications.
Haemochromatosis is the most common genetic disorder in Northern Ireland, primarily affecting individuals of Irish and Scottish descent. At its core, it's a condition where the body absorbs too much iron from food. While iron is essential for many bodily functions, excessive iron can accumulate in organs like the liver, heart, and pancreas, leading to significant damage over time. Think of it like slowly rusting from the inside out. Symptoms can be subtle and easily dismissed, ranging from persistent fatigue and joint pain to memory problems, abdominal discomfort, and skin issues. And this is the part most people miss: because the symptoms are so vague, people often attribute them to stress, aging, or other common ailments, delaying crucial diagnosis and treatment.
BBC News NI previously highlighted concerns that insufficient testing was occurring due to cost limitations. The current policy of the Department of Health focuses on screening individuals only after they exhibit symptoms.
But here's where it gets controversial... Is waiting for symptoms to appear really the best approach? Some argue that early detection and intervention could prevent irreversible organ damage and improve long-term health outcomes. Haemochromatosis UK champions proactive testing, aiming to identify individuals before they develop symptoms and experience the potentially devastating consequences of iron overload.
To address this gap, Haemochromatosis UK is launching a targeted initiative, offering free genetic screening to approximately 23,500 households in Irvinestown, Portadown, Ballymena, and Magherafelt. This proactive approach aims to gather crucial data and identify undiagnosed cases in areas where anecdotal evidence suggests higher prevalence rates. Neil Irwin, who works for Haemochromatosis UK and was diagnosed with the condition himself, emphasizes that early diagnosis is paramount, enabling access to effective treatments and preventing long-term complications. "In recent years we have had anecdotal evidence from areas like Mid Ulster where people have been contacting us saying their area seems to have high rates of haemochromatosis," he explains. "But there is a lack of official data, so we're looking to fill in some of those blank spots in Northern Ireland that have never screened before, to paint a more detailed picture of the prevalence of the condition."
Collette McKnight, a mother of three from rural County Down, shares her experience. Diagnosed in 2019, she initially attributed her severe fatigue and pains to the demands of motherhood. "But then I started to develop heart palpitations and I knew something else was wrong," she recounts. Upon receiving her diagnosis, she was unfamiliar with haemochromatosis. Now treated with therapeutic blood removal (phlebotomy), which helps lower iron levels, she manages her symptoms, which vary daily but consistently include debilitating fatigue.
The term "Celtic Curse" stems from the belief that the gene mutation responsible for most cases of hereditary haemochromatosis originated within the Celtic population of Europe. Genetic analysis has traced the presence of this mutation back to the Bronze Age, with evidence found in remains discovered on Rathlin Island, off the coast of County Antrim. Even further back, remains of a Neolithic woman found near Belfast carried a different variant of the gene. This suggests the genetic predisposition to iron overload has been present in the region for millennia.
To raise awareness, Haemochromatosis UK is touring a photographic exhibition titled "We are Overloaded" throughout Northern Ireland. Opening at the Millennium Court in Portadown on January 19th, the exhibition features powerful portraits by Pulitzer Prize-winning photojournalist Cathal McNaughton, showcasing individuals living with haemochromatosis. Finbar Polin, featured in the exhibition, shares his initial reaction to his diagnosis: "I'd never heard of the Celtic curse until I was diagnosed. It's scary initially because it affects you mentally; you don't know where you are going with it, but being part of the charity and meeting other people with it has really helped. That's where I think the exhibition is really powerful, each picture is a person with a story."
The Department of Health maintains that its screening policies are guided by the UK National Screening Committee (UK NSC). The UK NSC has stated that there's "limited evidence on whether treatment is more effective in individuals without symptoms, compared with those who have symptoms." However, Haemochromatosis UK argues that a comprehensive understanding of the condition's prevalence is crucial for effective public health strategies. Their research suggests that as many as one in ten people in Northern Ireland may be at risk of genetic haemochromatosis. The charity has previously funded and distributed free self-test kits in Belfast, Carrickfergus, and Londonderry.
These genetic testing kits, typically costing around £130, are now being offered free of charge thanks to donations and funding received by Haemochromatosis UK. James Hagan, founder of Hagan Homes, is among the donors, motivated by the recent diagnosis of someone close to him who had no symptoms. "Their experience highlights exactly why this campaign is so important. Most people affected have no warning signs, yet the potential consequences can be extremely serious if the condition goes undetected," he explains.
In the coming weeks and months, households in the designated postcode areas will receive information regarding genetic haemochromatosis, including an offer for a free genetic test and access to counseling to help them interpret their results.
This initiative raises some important questions: Should genetic screening for haemochromatosis be more widely available, even for those without symptoms? Is the current approach of waiting for symptoms adequate, or are we missing opportunities for early intervention and prevention?
