hypotonia) that can range from mild to severe. The muscle problems impair the development of motor skills such as sitting, standing, and walking, and may disrupt primary functions such as breathing and feeding. X-linked myotubular myopathy is a member of a group of disorders called centronuclear myopathies. In these conditions, as the name suggests, the nucleus is found in the center of the muscle fibers instead of around the periphery, as is normally the case. It is caused by mutations in the MTM1 gene and is inherited in an X-linked recessive pattern, occurring almost exclusively in males.X-linked myotubular myopathy is a condition that primarily affects skeletal muscles, the muscles used for movement. People with this condition have muscle weakness (myopathy) and decreased muscle tone (
