Continuous Muscle Fiber Activity Hereditary

Isaac's syndrome


Type of disease: Rare conditions

Isaac’s syndrome is a neuromuscular disease caused by continuous signaling of the end regions of peripheral nerve fibers that activate muscle fibers (motor neurons). Age of onset is between ages 15 and 60, with most patients experiencing symptoms before age 40. There are hereditary and acquired forms of the disorder. The acquired form may develop in association with peripheral neuropathies or as an autoimmune condition.
