Genetic Study Reveals Elevated Risk Among Scottish Travellers
Professor Jim Wilson led the first comprehensive genetic study of Scottish Travellers, revealing that certain individuals within the community face a significantly increased risk of rare inherited diseases compared to the general Scottish population.
Although the majority of the community are not affected, a small subset is at risk of five uncommon conditions, including a specific form of kidney disease and a blood disorder.
Researchers from the University of Edinburgh emphasized the need for community-led genetic screening initiatives and heightened awareness among healthcare professionals.
Members of the Traveller community who participated in the study highlighted that any further disease testing should be conducted respectfully and collaboratively with the community.
Origins and Genetic Findings
Scottish Traveller Samantha Whyte Donaldson initially requested the University of Edinburgh to perform DNA analysis to investigate the community's origins.
Between 2021 and 2022, scientists collected saliva samples from 125 individuals who had at least two Traveller grandparents.
The study found that Scottish Travellers possess strong Scottish ancestral roots and identified a 2,500-fold increased risk of one specific genetic mutation linked to a rare kidney disorder.
Despite this elevated risk, researchers stressed that these rare diseases remain very uncommon within the community.
Research Leadership and Health Inequalities
Jim Flett Wilson, Professor of Human Genetics at the University of Edinburgh's Usher Institute and lead investigator, stated the importance of this research in addressing persistent health disparities.
"Every population I've looked at has its own set of genetic risks,"
Professor Wilson has previously studied small communities, identifying increased cancer risks in Orkney and Shetland.
He hopes that understanding the specific risks faced by Scottish Travellers will enable the development of tailored community testing and improved healthcare services.
Community Perspectives and Health Challenges
Samantha Whyte Donaldson expressed optimism that the research could help combat discrimination and improve health outcomes, provided the community remains involved.
"Unfortunately Scottish travellers do have a shorter life expectancy compared to the settled population,"
"Prejudice and discrimination is one part of it but health disparities are another, so I'm hoping the Scottish government sees this and thinks: 'What can we do in terms of things like screening programmes'?"
Historically, the Scottish Travelling community has faced centuries of discrimination and exclusion, resulting in reluctance to engage with health services or participate in scientific studies.
According to the 2022 census, 3,343 people in Scotland identified as Gypsy or Traveller. While some continue seasonal travel, most reside in permanent housing or designated sites across Scotland.
In 2022, First Minister John Swinney issued an apology for the "Tinker Experiments," a series of forced settlement policies from the 1940s to 1980s that also involved removing children from their families.
Samantha's mother was among those taken into care as a child and endured racial abuse.
"They really drummed into her that her people were scum and she grew up very much assimilated,"
Genetic Ancestry and Community Identity
The lack of comprehensive data has contributed to misunderstandings about the Scottish Travellers, including incorrect assumptions that they descended from Romani or Pictish populations.
The study identified two major genetic subgroups within the community, likely reflecting Highland and Lowland Scottish ancestry.
Jess Smith, aged 78, an elder and storyteller within the Traveller community, welcomed the findings.
"I don't really want to be anything other than Scottish and I will stand up in any platform and say I'm a Scot,"
"You've only got to look at the Tartan Army. Is that not people proud of their roots that they belong to?
Well, we all belong to that now, the travellers as well,"
Jess Smith's comments highlight the community's strong identification with Scottish heritage.
