Dystrophin is a large cytoskeletal protein that is required for the structural integrity of muscle fibers and helps in transmitting force from the extracellular matrix to the muscle fiber. Mutations in the DMD (dystrophin) gene result in a deficiency or abnormality of dystrophin protein, which leads to progressive muscle weakness and ultimately to muscle wasting. The symptoms of dystrophinopathy can vary from mild to severe, and the disease can be classified into several subtypes, including Duchenne muscular dystrophy, Becker muscular dystrophy, and X-linked dilated cardiomyopathy. Although dystrophinopathy has been extensively studied, much remains to be understood about the molecular biology and clinical manifestations of the disorder.Research QuestionThe research question of this study is to investigate the molecular biology and clinical presentations of dystrophinopathy. Specifically, the study aims to answer the following questions:1. What are the molecular mechanisms that underlie the development of dystrophinopathy?2. How do different types of mutations in the DMD gene contribute to the pathogenesis of dystrophinopathy?3. What are the clinical features of dystrophinopathy, and how do they differ among the various subtypes of the disorder?4. What are the current treatments for dystrophinopathy, and what are their limitations?Literature ReviewDystrophin, a 427 kDa protein, is the largest known cytoskeletal protein and is found primarily in skeletal and cardiac muscle. Dystrophin serves as a l...
