Tuberous sclerosis complex is a genetic disorder characterized by the growth of numerous noncancerous (benign) tumors in many parts of the body. Tuberous sclerosis (TWO-bur-uhs skluh-ROH-sis), also called tuberous sclerosis complex, is an uncommon genetic disorder that causes noncancerous (benign) tumors — unexpected overgrowths of normal tissue — to develop in many parts of the body. /CA 1.0 Tuberous sclerosis complex (TSC) is a highly variable condition whose features include numerous benign tumors of the skin, brain, kidneys, lungs, heart, and other organs.TSC can also cause mild-to-severe neurodevelopmental and behavioral impairments, often manifesting as autism spectrum disorder.. << First described in the 1880s by French neurologist Désiré-Magloire Bourneville, tuberous sclerosis complex (TSC) is a genetic disorder that causes tumors to form in many different organs, primarily in the brain, eyes, heart, kidney, skin and lungs. The name arises from the potato stem-shaped growths that occur in the brain, also known as tubers. For a patient to demonstrate features of both tuberous sclerosis and Proteus syndrome, he/she must have both a germline mutation (for tuberous sclerosis) as well as a postzygotic mutation (for Proteus syndrome) of this shared pathway.
