Tuberous sclerosis complex (TSC) is a childhood-onset disorder with characteristic dermatological findings, tumors, epilepsy, and developmental delay owing to pathogenic genetic variants in the TSC1 (hamartin) or TSC2 (tuberin) genes. Picture of Tuberous Sclerosis (Adenoma Sebaceum) Tuberous sclerosis, adenoma sebaceum. Tuberous sclerosis complex (TSC) is an autosomal dominant disorder that affects multiple organ systems due to an inactivating variant in either TSC1 or TSC2, resulting in the hyperactivation of the mechanistic target of rapamycin (mTOR) pathway.Dysregulated mTOR signaling results in increased cell growth and proliferation. Although TSC remains a heterogeneous clinical entity, the recent inclusion of … Other symptoms become more obvious in childhood, such as developmental delay and skin changes. Tuberous sclerosis complex is a multisystemic, autosomal dominant genetic disorder with complete penetrance, that can evolve with hamartomas in multiple organs, such as skin, central nervous system, kidney and lung.
