Scottish Travellers Found to Have Higher Risk of Certain Rare Genetic Diseases, Landmark Study Reveals

A landmark genetic study has found that some Scottish Travellers face a significantly higher risk of several rare inherited diseases compared with the wider Scottish population. Researchers say the findings could help improve healthcare through targeted genetic screening, earlier diagnosis, and greater awareness among medical professionals.

The research, led by scientists at the University of Edinburgh, is the first major genetic study focused specifically on the Scottish Traveller community. While experts emphasize that the vast majority of Scottish Travellers are not affected by these conditions, the study identified a notably increased likelihood of carrying certain rare genetic mutations.

The findings also shed new light on the community's ancestry, confirming deep Scottish roots and identifying distinct Highland and Lowland genetic lineages.

Landmark Genetic Study Focuses on Scottish Travellers

Researchers collected saliva samples from 125 individuals between 2021 and 2022. Participants all had at least two Scottish Traveller grandparents, allowing scientists to examine genetic patterns unique to the community.

The project was initiated after Scottish Traveller Samantha Whyte Donaldson approached researchers, asking them to investigate the origins and genetic history of Scottish Travellers.

Rather than focusing solely on ancestry, the research also uncovered important health information that could influence future medical care.

Higher Risk of Five Rare Inherited Diseases

Scientists found that a small proportion of Scottish Travellers have an increased risk of five rare inherited conditions.

Among the most significant findings was a genetic mutation linked to a rare kidney disorder. According to researchers, this particular mutation is estimated to be around 2,500 times more common among Scottish Travellers than in the general Scottish population.

The study also identified elevated risks for several other uncommon inherited conditions, including a rare blood disorder.

However, researchers stressed that these diseases remain extremely rare overall. Even though the relative risk is much higher, only a small number of people within the Traveller community are expected to develop the conditions.

This distinction is important because a higher statistical risk does not mean that most Scottish Travellers will experience these illnesses.

Why Genetic Screening Could Make a Difference

Professor Jim Wilson, who led the research at the University of Edinburgh's Usher Institute, believes the findings highlight the importance of community-led genetic screening programmes.

According to the research team, identifying individuals who carry these mutations could lead to:

• Earlier diagnosis of inherited diseases
• Better monitoring of people at higher risk
• Improved treatment outcomes
• More informed family planning decisions
• Greater awareness among healthcare professionals

Professor Wilson noted that every population has its own unique genetic profile, and understanding those differences can help reduce health inequalities.

His previous research has identified increased genetic risks for certain cancers in communities in Orkney and Shetland, demonstrating how localized genetic studies can improve public health strategies.

Community Involvement Was Central to the Research

One of the defining aspects of the study was the involvement of the Traveller community throughout the process.

Samantha Whyte Donaldson supported the research because she believes better understanding of genetic health could help address longstanding healthcare inequalities.

She also emphasized that any future genetic screening programmes should be developed respectfully and in partnership with the Traveller community.

This collaborative approach is particularly important given the community's historical experiences with discrimination and mistrust of public institutions.

Addressing Longstanding Health Inequalities

Scottish Travellers experience a shorter average life expectancy than the settled population, with experts attributing this to multiple factors.

These include:

• Limited access to healthcare
• Health inequalities
• Social exclusion
• Historical discrimination
• Reluctance to engage with health services

Researchers hope the study will encourage policymakers to consider tailored healthcare initiatives that better meet the needs of Scottish Travellers.

Improved awareness among clinicians may also reduce delays in diagnosing rare inherited conditions.

Historical Discrimination Still Shapes Healthcare

The relationship between Scottish Travellers and public services has been shaped by decades of discrimination.

Many families remain affected by policies introduced between the 1940s and 1980s, commonly referred to as the "Tinker Experiments." During this period, authorities attempted to forcibly settle Traveller families and removed many children from their parents.

In 2025, Scotland's First Minister John Swinney issued a formal apology for these historic actions.

Samantha Whyte Donaldson has spoken publicly about her family's experiences, explaining that her mother was taken into care as a child and faced racist abuse because of her Traveller background.

Researchers acknowledge that this history has contributed to understandable hesitancy among some community members when participating in scientific research or healthcare programmes.

New Evidence Confirms Scottish Ancestry

Alongside its health findings, the study also provided important insights into Scottish Traveller ancestry.

For many years, there were misconceptions that Scottish Travellers primarily descended from Romani or ancient Pictish populations.

Instead, the genetic analysis revealed strong and longstanding Scottish roots.

Researchers also identified two major genetic subgroups within the community, which likely reflect Highland and Lowland ancestry.

These findings help strengthen historical understanding of one of Scotland's oldest indigenous minority communities.

Community Leaders Welcome the Findings

Traveller elder and storyteller Jess Smith welcomed the research, saying it reinforces what many within the community have always believed about their Scottish identity.

The study provides scientific evidence supporting the community's deep historical connection to Scotland while also highlighting healthcare needs that may have been overlooked for generations.

Community representatives hope the findings will encourage greater recognition, respect, and inclusion.

What Happens Next?

Researchers believe the study should serve as a starting point rather than an endpoint.

Future priorities may include expanding genetic research with larger participant groups, improving clinician awareness of rare inherited diseases affecting Scottish Travellers, and developing voluntary community-based genetic screening programmes.

Scientists also stress that any future initiatives should continue to involve Traveller communities directly to ensure trust, transparency, and culturally appropriate healthcare.

If implemented carefully, the findings could help reduce health inequalities while improving diagnosis and treatment for individuals who carry rare inherited genetic mutations.

Conclusion

The University of Edinburgh's landmark study represents a significant step forward in understanding both the genetic heritage and healthcare needs of Scottish Travellers.

Although the research identified an increased risk for several rare inherited diseases, experts emphasize that these conditions remain uncommon and affect only a small number of people. The findings instead offer an opportunity to improve healthcare through earlier diagnosis, informed screening, and stronger partnerships between medical professionals and the Traveller community.

Beyond its medical significance, the study also provides valuable evidence confirming the community's deep Scottish ancestry, helping challenge longstanding misconceptions while supporting efforts to address historical inequalities.
