Millions of individuals in the UK living with rare genetic disorders are finding themselves overlooked by the National Health Service (NHS), according to a recent report by Genetic Alliance UK. This study highlights the struggles faced by those with conditions such as Williams syndrome and Duchenne muscular dystrophy, revealing alarming statistics about diagnosis delays and treatment accessibility.
A Struggle for Diagnosis
The report, which surveyed 290 individuals affected by rare conditions, uncovered that a staggering one in four respondents waited over three years for a diagnosis despite seeking help from NHS professionals. This is a startling reality for many families, including that of Ali Reed, whose daughter Emma has Williams syndrome—a condition that affects approximately one in 18,000 people in the UK.
Reed recalls the painful journey they undertook before Emma’s diagnosis. “It wasn’t until Emma was nine months old that anyone questioned her development,” she shared. “And it took another year before we received the diagnosis. It was baffling to have multiple healthcare professionals who had experience with Williams syndrome yet fail to see it in Emma.”
Despite the challenges, Emma has been fortunate to receive consistent care from the same paediatrician for 13 years. However, as she prepares to transition into adult care, there are genuine concerns about the quality of treatment she will receive. Reed highlights the worrying statistic that only about one in thirty GPs have any knowledge of Williams syndrome, raising fears that her daughter may not receive the comprehensive care she needs.
The ‘Access Lottery’ of Treatments
The report further identifies an “access lottery” when it comes to treatments for rare conditions. Only five per cent of these conditions have therapies that have been formally approved and licensed. This lack of available treatment options can leave families feeling helpless and frustrated, as they navigate a healthcare system that often seems indifferent to their needs.

Nick Meade, the Chief Executive of Genetic Alliance UK, emphasised that while the NHS generally excels in many areas, it often falls short for those with rare genetic conditions. “Our healthcare model is designed around common conditions, which means that when you encounter a rare and complex condition, the pathways for care are rigid and often inadequate,” he explained. “People living with rare conditions are essentially penalised for having complex needs that don’t fit neatly into existing frameworks.”
The Need for Systematic Change
An analysis of 163 prevalent rare conditions from the European Orphanet database revealed that only 26 per cent are supported by guidance from the National Institute for Health and Care Excellence (NICE). Alarmingly, more than half of the conditions that had identifiable commissioners in England lacked specialised services, leaving many patients and families to fend for themselves.
In light of these findings, Genetic Alliance UK has called for a comprehensive registry for rare conditions to be established across the UK, alongside increased investment in research and treatment options. This could pave the way for improved care pathways and a better understanding of these often-misunderstood conditions.
Why it Matters
The plight of those with rare genetic conditions underlines a significant gap in the NHS’s approach to healthcare. By failing to adequately address the needs of these individuals, the system not only jeopardises their health and wellbeing but also places an emotional burden on families navigating a complex landscape. The call for reform is urgent; as the report suggests, without systematic changes, millions will continue to face delays and inadequate care, reinforcing the need for a more inclusive and responsive healthcare model.
