Clinical information about G71.220 ICD 10 code

X-linked myotubular myopathy is a condition that primarily affects muscles used for movement (skeletal muscles) and occurs almost exclusively in males. People with this condition have muscle weakness (myopathy) and decreased muscle tone (hypotonia) that are usually evident at birth. When viewed under a microscope, the muscle fibers of affected individuals are typically small and underdeveloped.

The muscle problems in X-linked myotubular myopathy impair the development of motor skills such as sitting, standing, and walking. Affected infants may also have difficulties with feeding due to muscle weakness. Individuals with this condition often do not have the muscle strength to breathe regularly on their own and must be supported with a machine to help them get enough oxygen (mechanical ventilation). Some affected individuals need breathing assistance only periodically, typically during sleep, while others require it continuously. People with X-linked myotubular myopathy may also have weakness in the muscles that control eye movement (ophthalmoplegia), weakness in other muscles of the face, and absent reflexes (areflexia).

In X-linked myotubular myopathy, muscle weakness often disrupts normal bone development and can lead to fragile bones, an abnormal curvature of the spine (scoliosis), and joint deformities (contractures) of the hips and knees. People with X-linked myotubular myopathy may have a large head with a narrow and elongated face and a high, arched roof of the mouth (palate). They may also have recurrent ear and respiratory infections, seizures, or liver disease. Some affected individuals develop a serious liver condition called peliosis hepatitis, which can cause life-threatening bleeding (hemorrhage).

Because of their severe breathing problems, individuals with X-linked myotubular myopathy usually survive only into early childhood; however, some people with this condition have lived into adulthood.

X-linked myotubular myopathy is the most severe condition in a group of disorders called centronuclear myopathy. In centronuclear myopathy, the nucleus is found at the center of many rod-shaped muscle cells instead of at either end, where it is normally located.
