On April 10, 2025, Morocco reached a milestone in biomedical research with the publication of the first results from the Moroccan Genome Project (MGP) in Communications Biology, part of the Nature group. This pioneering study lays the groundwork for a national reference genome, a crucial tool for developing precision medicine tailored to the genetic specifics of Moroccans. Led by the Mohammed VI Foundation for Health Sciences through its Research and Innovation Center (CM6RI), the project involved the complete sequencing of the genomes of 109 individuals from various regions of the Kingdom. The result: more than 27 million genetic variants identified, including 1.4 million previously unknown worldwide. Researchers highlighted 15,378 frequent mutations unique to the Moroccan population and designed a reference genome named MMARG (Moroccan Major Allele Reference Genome), which is more representative than the international standard GRCh38, which is not well-suited to local peculiarities. Drawing on expertise in genomics, bioinformatics, and medicine, this work also relied on advanced systems for secure data management. It marks a major step toward a better understanding of the hereditary factors of diseases in the country. The next phase of the program plans to expand the cohort analyzed to refine this genetic reference model and strengthen the foundations of personalized medicine in Morocco.
