Muscular dystrophies are classified into different types based on their age of onset, clinical severity, rate of progression, distribution of muscles weakness, pattern of inheritance and the genes involved. As muscular dystrophies are relatively uncommon disorders, very little work has been done in Pakistan. This study has classified (for the first time in Pakistan) the patients with different types of muscular dystrophies by clinical and biochemical correlation. Study Design: Observational, descriptive study.
