Summary. 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. Mutations in this gene lead to tuberous sclerosis.Its gene product is believed to be a tumor suppressor and is able to stimulate specific GTPases.Hamartin coded by the gene TSC1 functions as a facilitator of Hsp90 in chaperoning of Tuberin, therefore preventing its ubiquitination and degradation in the proteasome. Accurate diagnosis is fundamental to implementation of appropriate medical surveillance and treatment. In: Adam MP, Ardinger HH, Pagon RA, Wallace SE, Bean LJH, Mirzaa G, Amemiya A, editors.
