The Genes & Health study has marked a pivotal moment in UK genomics research with the launch of a major new initiative on April 11, aimed at closing persistent health gaps experienced by South Asian communities. This expansion builds on years of groundbreaking work, bringing advanced genetic insights directly to underserved populations in regions like the West Midlands.
British people of Pakistani and Bangladeshi heritage face disproportionately high rates of conditions such as type 2 diabetes and cardiovascular disease—up to four times higher than the general population. By sequencing DNA from thousands more volunteers, researchers hope to uncover the genetic factors driving these disparities, paving the way for tailored diagnostics, treatments, and preventive strategies.
Understanding the Genes & Health Project's Origins and Evolution
Genes & Health, spearheaded by Queen Mary University of London's Blizard Institute, represents the world's largest community-led genetics study focused on British Bangladeshi and Pakistani populations. Launched initially in East London, Bradford, and Manchester, it has already recruited over 55,000 volunteers who provided saliva samples for whole-genome sequencing—a process that maps the entire three billion DNA base pairs in an individual's genome to identify variants linked to disease risk.
The project's community-centric approach sets it apart. Volunteers not only contribute DNA but also health data via questionnaires, creating a rich dataset that combines genetics with lifestyle and environmental factors. This holistic method has enabled discoveries like novel gene variants accelerating type 2 diabetes onset in South Asians, published in high-impact journals such as Nature Medicine.
Funding from the Wellcome Trust, Medical Research Council (MRC), and NHS partners has fueled its growth, with ambitions to reach 100,000 participants. The April 11 initiative extends recruitment to new areas, ensuring broader representation.
Health Disparities Facing UK South Asian Communities
South Asians in the UK experience stark health inequities. Type 2 diabetes prevalence is 2-6 times higher than in white Europeans, while cardiovascular disease strikes a decade earlier on average. Heart disease mortality is 50% higher in British Pakistanis, compounded by factors like consanguineous marriages increasing rare genetic disorders.
- Diabetes: Up to 4-fold risk, with earlier onset and complications like kidney failure.
- Cardiovascular disease: 2-3 fold elevated risk, driven partly by genetics.
- Other conditions: Higher rates of chronic kidney disease, liver disease, and mental health issues.
These gaps stem from a mix of genetics, socio-economic factors, diet, and underrepresentation in prior research, which was 95% European-focused. Genes & Health addresses this by prioritizing non-European genomes.
Queen Mary University of London's Pivotal Role
At the helm is Queen Mary University of London (QMUL), a leader in genomic medicine. Professor David van Heel, a genetics expert at the Blizard Institute, oversees the project alongside Dr. Sarah Finer, a diabetes specialist. Their team has transformed raw DNA data into actionable insights, such as identifying hypercholesterolemia genes that prompted recalls for life-saving statins in 50 patients.
QMUL's multidisciplinary approach integrates bioinformatics, epidemiology, and clinical trials. Collaborations with the Alan Turing Institute enhance AI-driven analysis, spotting subtle genetic signals missed by traditional methods. This academic leadership exemplifies how universities drive precision medicine.Learn more about QMUL's contributions
Scientific Methodology: From Saliva to Insights
Participation is straightforward: Volunteers aged 16+ provide a saliva sample at pop-up clinics or home kits, alongside health questionnaires. DNA undergoes whole-genome sequencing at scale, analyzed via genome-wide association studies (GWAS)—statistical methods linking genetic variants to traits.
Step-by-step process:
- Recruitment: Community events, GP referrals, mosques/temples.
- Sequencing: High-throughput platforms read genomes at 30x coverage.
- Analysis: Polygenic risk scores predict disease susceptibility.
- Return of findings: Clinically actionable results shared with participants/NHS.
This pipeline has yielded over 100 novel associations for heart disease.

Past Achievements and Real-World Impact
Genes & Health has delivered tangible benefits. Key discoveries include:
- 22 genetic loci unique to South Asian type 2 diabetes, enabling risk prediction models.
- Familial hypercholesterolemia variants, leading to preventive treatments averting heart attacks.
- Blood biomarker genetics, informing routine NHS tests.
Over 20 peer-reviewed papers in Nature Genetics, Cell, and The Lancet have emerged, influencing global guidelines. Participants report empowerment, with 90% willing to share results for family health.
| Discovery | Impact |
|---|---|
| Type 2 Diabetes Genes | Earlier screening in high-risk families |
| Hypercholesterolemia | 50 patients treated preventively |
| Heart Disease Variants | 100+ new links identified |
The April 11 Expansion: West Midlands Focus
The new phase targets Wolverhampton and Walsall, partnering with Royal Wolverhampton NHS Trust and Walsall Healthcare NHS Trust. Clinics at Walsall Manor and New Cross Hospitals will recruit hundreds more.
Fahad Hossain, consultant at Walsall Manor, emphasized: "The research we do today will make an enormous impact on generations to come." Professor Tonny Veenith added pride in contributing to underrepresented research.Read the full BBC coverage
Community Engagement and Ethical Considerations
Trust-building is core. Community advisors from mosques and cultural groups co-design outreach. Informed consent covers data use, with opt-outs anytime. Ethical oversight by MRC ensures equity—no commercial exploitation without benefit-sharing.
Benefits for participants:
- Personalized health reports.
- Family risk notifications.
- Contribution to equitable medicine.
To join: Visit genesandhealth.org or local NHS events.
Future Directions: Beyond Diabetes and Heart Disease
With 100,000 genomes, focus shifts to mental health, dementia, pregnancy complications, and rare diseases. AI integration will accelerate polygenic scoring for NHS implementation. Long-term, it could inspire similar projects globally, reducing ethnic health gaps.
Universities like QMUL are training next-gen researchers in diverse genomics, vital for UK's life sciences sector.
Implications for Precision Medicine and Higher Education
This initiative underscores universities' role in translational research. QMUL's model—academia-NHS-community—could standardize inclusive genomics. For academics, it opens doors in bioinformatics, epidemiology, and ethical AI.
Stakeholders praise its multi-perspective approach, balancing science with cultural sensitivity.
