Welcome. Myotubular Myopathy is a rare muscle condition which affects mostly boys at birth, and sometimes an even rarer form develops later in life affecting both boys and girls. It causes profound muscle weakness.
Many of the inherited myopathies are caused by mutations that interfere with ion channels, causing either too much or too little current from flowing through the muscle cells. These disorders (myotonia congenita, paramyotonia congenita, periodic paralysis and central core disease) are sometimes called channelopathies. Central core disease seems to damage, and thus weaken, muscles by causing an excess release of calcium from internal storage compartments. A fifth myopathy, nemaline myopathy, is caused by mutations that affect filament proteins.
