In Morocco, whole exome sequencing (WES) is now enabling faster and more accurate diagnoses of genetic diseases. This high-throughput technology (NGS), introduced for the first time in the country, is unlocking revolutionary possibilities in the field of genetics, making it possible to identify up to 85% of mutations responsible for complex or hereditary diseases. The genetic test is available at the Anoual Centre laboratory in Casablanca, which describes it as a «promising new diagnostic tool» that offers «more precise and faster medical care». The process involves analyzing more than 20,000 human genes in a single step, using a sample of saliva, blood, or any other biological material containing DNA. Sequencing provides a «comprehensive and rapid genome analysis», reducing wait times and uncertainty, while detecting multiple genetic mutations in one test. «This test plays a crucial role in identifying the genetic causes of various pathologies, enabling timely treatment decisions and preventing inappropriate treatments», the laboratory emphasized in a statement. The pilot phase lasted over a year and was conducted via the dedicated molecular biology platform «GENOMAf» (Genome of Africa). This breakthrough complements the Moroccan Genome Project (PGM), led by the Mohammed VI Foundation for Health Sciences, which aims to establish a national reference genome and develop precision medicine tailored to local genetic characteristics.
