Dubai's Bold Step in Genomic Screening: MBRU-Led Study Graces Nature Medicine Cover
Dubai Health and Mohammed Bin Rashid University of Medicine and Health Sciences (MBRU) have etched a significant milestone in global medical research with a groundbreaking study featured on the cover of Nature Medicine, one of the world's most prestigious peer-reviewed journals. Published on April 21, 2026, the paper titled "Citywide premarital genomic screening in a Middle Eastern population" highlights the feasibility and impact of Dubai's mandatory premarital genomic screening program for Emirati nationals. This achievement underscores UAE's commitment to precision medicine, blending cutting-edge science with public health strategy in a region with high consanguinity rates.
The study, led by first author Khulood Alblooshi, an Emirati second-year MSc Biomedical Sciences student at MBRU, details screening of 1,000 couples (2,000 individuals) across 18 primary healthcare centers (PHCs) in Dubai. Using targeted sequencing of 782 genes linked to severe autosomal recessive disorders, researchers identified 79 at-risk couples (8%, 95% CI: 6.4–9.7%), a rate notably higher than the 3.9% in Australia's Mackenzie’s Mission. Hemoglobinopathies dominated (41%), but 59% involved diverse genes, including population-specific variants from Dubai's genomic database.
MBRU and Dubai Health: Forging an Integrated Academic Health Powerhouse
MBRU, established in 2016 as Dubai's pioneering graduate-level medical university, forms the academic backbone of this collaboration with Dubai Health. Together, they operate within an integrated academic health system that seamlessly links clinical care, education, and discovery. Since inception, their researchers have authored 2,362 papers in top journals, with several scientists ranking in Stanford's top 2% most-cited globally for four years running.
Dr. Amer Sharif, CEO of Dubai Health and President of MBRU, emphasized, "We are proud of the progress achieved, made possible by the vision of our leadership... We remain committed to empowering our talent to produce impactful research." This synergy is supported by 10 specialized research centers, fostering multidisciplinary work from genomics to clinical translation.

Unpacking the Study: Methods and Groundbreaking Findings
The program, launched January 2025, mandates screening for Emiratis via PHCs or the DubaiNow app. Blood samples undergo whole-exome or whole-genome sequencing at Dubai Health's Genomic Medicine Center, focusing on a curated 782-gene panel: 558 UAE-mandated severe disease genes plus 224 locally prioritized variants. Coverage exceeded 99% at ≥10× depth, with a 1.9% analytical failure rate and 11.9–14.6-day turnaround.
- At-risk identification: 79 couples shared pathogenic/likely pathogenic variants; 63.8% identical variants, linked to 28% genomic consanguinity (vs. self-reported 39.9%).
- Undiagnosed cases: 4 homozygous carriers (2.5% of carriers), revealing conditions like VPS13A disease and congenital adrenal hyperplasia.
- Interventions: 80% proceeded to marriage with free IVF/preimplantation genetic testing (PGT-M) via Al Amal Initiative; 20% opted out.
Surveys revealed 88.7% couple satisfaction, though 67.9% reported anxiety. Providers praised feasibility (100% positive), noting education gaps. Read the full open-access paper here for detailed workflows and figures.
Precision Medicine in Action: Reducing Rare Disease Burden in UAE
In consanguineous populations like UAE's Emiratis, autosomal recessive disorders pose significant risks. Dubai's program addresses this proactively, potentially slashing incidence via early detection and interventions. Compared to voluntary programs, mandatory screening boosts uptake, with hemoglobinopathies (α/β-thalassemia, sickle cell) comprising 41% risks—addressable via simple tests plus sequencing.
Local adaptations proved crucial: 18% risks from Dubai-specific genes would evade standard panels. Long-term, this feeds national registries for variant reclassification and policy refinement, aligning with UAE's Emirati Genome Program and 100,000 Genomes Project.
| Metric | Dubai Program | Australia (Mackenzie’s) |
|---|---|---|
| At-risk Couples (%) | 8% | 3.9% |
| Couples Screened | 1,000 | Large cohort |
| Key Diseases | Hemoglobinopathies (41%) | Various recessive |
This data-driven approach exemplifies cost-effective prevention, with IVF/PGT-M subsidies ensuring equity.

Challenges, Perceptions, and Path Forward
Despite successes, hurdles persist: reference biases, short-read limits for homologous genes, and emotional impacts like anxiety. Future steps include long-read sequencing, AI integration, and expanded panels. Longitudinal tracking will quantify disease reduction, optimizing costs (e.g., targeted 4-variant + thalassemia screen detects 54%).
Stakeholder views: 88.7% couples value screening; providers note scalability but urge better education. Sheikh Ahmed bin Saeed: "Significant milestone in Dubai's research landscape."
