Abstract:

Duchenne muscular dystrophy (DMD) is a hereditary, progressive muscular disorder inherited in an X-linked recessive pattern (Xp21). It typically manifests in childhood and follows a severe, rapid progression. Only males are affected, while females are usually carriers. Given the genetic nature of DMD, genetic counseling is an essential service for individuals affected by or at risk of carrying the disease. This service provides not only crucial medical information but also psychosocial support and ongoing management for both patients and their families. Since the discovery of the dystrophin gene in 1987, advancements in molecular genetics have made it possible to precisely identify the genes responsible for many neuromuscular diseases. These developments have revolutionized diagnosis, prognosis, and most importantly, genetic counseling, offering significant benefits for both patients and their families. To highlight the significance of these advancements, this case report focuses on a 10-year-old boy (Y) diagnosed with DMD. It emphasizes the familial nature of the disease, with Y’s two brothers, three cousins, and two maternal uncles also affected, underscoring the inherited pattern of DMD. This reinforces the critical need for early intervention, particularly in regions with high consanguinity, such as North Africa and the Middle East, where genetic counseling and prenatal diagnosis are even more essential. Additionally, the report explores the clinical presentation, diagnostic findings, and promising emerging treatments, including RNA-based therapies, which may play a key role in the future management of DMD. In light of the above, this study underscores the importance of prenatal diagnosis and genetic counseling, particularly in regions like Morocco, where consanguinity rates are notably high. By focusing on preconception care and early genetic intervention, families can be better informed, leading to more effective disease management and support.
