MENA/Levant Epidemiological, Registry of Immunological & Clinical Traits (MERIT)

The primary objective of this multicenter observational registry is to characterize the clinical, epidemiological, and biological profiles of individuals of Middle Eastern, North African, and Levantine ancestry, including individuals with chronic medical conditions and healthy volunteers. The registry will collect standardized clinical and participant-reported data, along with biological samples, to support the investigation of disease patterns, health-related characteristics, and population-specific biological and immunological profiles in populations historically underrepresented in biomedical research. The resulting data and samples may support future research into disease-associated biomarkers and underlying biological mechanisms.
