TSC1 mutations appear to be more common in familial cases of tuberous sclerosis complex, while mutations in the TSC2 gene occur more frequently in sporadic cases. 13 [updated 2020 Apr 16].  |  Tuberous sclerosis complex (TSC) is a genetic disease characterized by the growth of tumors, usually benign but occasionally malignant, in multiple organ systems of the body. In two thirds of cases, there is no family history of the condition … Tuberous sclerosis (TS), or tuberous sclerosis complex (TSC), is a rare genetic condition that causes noncancerous, or benign, tumors to grow in … Regarding the genetic sources of epilepsy, tuberous sclerosis complex is among the most common.

For some types of tumors to develop, a second mutation involving the other copy of the TSC1 or TSC2 gene must occur in certain cells during a person's lifetime.
