Kas distrofisi is a group of genetic disorders characterized by progressive weakness and degeneration of the skeletal muscles. These conditions are caused by mutations in genes responsible for muscle structure and function, leading to muscle wasting and loss of strength over time. There are several types of kas distrofisi, with Duchenne muscular dystrophy being one of the most common. Symptoms often appear in early childhood, and while there is currently no cure, treatments such as physical therapy and medications can help manage symptoms and improve quality of life.
