Clinical and Para clinical Manifestations of Tuberous Sclerosis: A Cross Sectional Study on 81 Pediatric Patients. The diagnosis of tuberous sclerosis is based on clinical features, but the distinction of types 1 and 2 requires molecular genetic analyses and the identification of mutations in the respective genes. 1986 Nov;37(6):543-5. doi: 10.1016/s0009-9260(86)80009-5. TSC causes the growth of non-malignant tumours to form in vital organs. Tuberous sclerosis is a genetic disorder affecting cellular differentiation and proliferation, which results in hamartoma formation in many organs (eg, skin, brain, eye, kidney, heart). Consequently, the revised criteria require tuberous sclerosis complex-associated lesions of two or more organ systems or at least two dissimilar lesions of the same organ to confirm the diagnosis.
