Adenylosuccinate synthetase-like 1-related distal myopathy

Adenylosuccinate synthetase-like 1-related distal myopathy, sometimes called ADSSL1 myopathy, is a rare inherited muscle disease caused by changes (mutations) in the ADSSL1 gene. This gene provides instructions for making an enzyme that plays an important role in energy production inside muscle cells. When this enzyme does not work properly, muscle cells — especially those in the hands, feet, and lower legs — gradually weaken and waste away over time. This type of muscle disease is called a 'distal myopathy' because it mainly affects the muscles farthest from the center of the body. People with this condition typically notice weakness and wasting in the muscles of the hands and lower legs, which can make everyday tasks like gripping objects, walking, or climbing stairs increasingly difficult. The disease usually begins in young adulthood, though the age of first symptoms can vary. Some people also experience muscle pain or cramping. The heart and breathing muscles are generally not affected in most reported cases, which is reassuring. There is currently no cure for ADSSL1 myopathy. Treatment focuses on managing symptoms and maintaining quality of life. Physical therapy, occupational therapy, and assistive devices such as braces or orthotics can help people stay as independent as possible. Regular monitoring by a neuromuscular specialist is important to track how the disease is progressing and to adjust care as needed.
