If one major criterion and one minor criterion are fulfilled, the patient may be diagnosed with probable tuberous sclerosis although this diagnostic class is no longer defined in the guidelines [1] [2]. Part of Springer Nature. Tuberous sclerosis complex (TSC) is a neurocutaneous syndrome that occurs in 1 of 6000 children; 85% of cases involve mutations in the TSC1 gene (9q34), which controls the production of hamartin, or the TSC2 gene (16p13.3), which controls the production of tuberin. They usuallyfirst developduring early childhood and can include: Mostpeople with tuberous sclerosis will have multiple growths in their kidneys, including tumours andcysts (small fluid-filled sacs). If such a pathogenic mutation is found then this alone is sufficient to diagnose TSC. Am J Gastroenterol. It is an autosomal dominant hereditary disorder, meaning a person only has to receive one copy of the abnormal gene from one of their parents to have the disease. pp 105-107 | If left untreated, it can cause brain damage or, in the most serious cases, death. The only comprehensive overview of the molecular basis and clinical features of the genetic disorder tuberous sclerosis, which affects approximately 50,000 people in the US alone. A pathogenic mutation in the gene prevents the proteins from being made or inactivates the proteins. Correct diagnosis of this syndrome is imperative, not only by detecting cutaneous manifestations at physical examination but also by recognizing the characteristic multimodality imaging findings. Philadelphia: Saunders; 2012. These keywords were added by machine and not by the authors. Tuberous sclerosis is a genetic disease characterized by nonmalignant tumor growth in all organs due to the inactivation of tumor growth suppressors. Tuberous sclerosis complex (TSC) is a dominant hereditary disease characterized by a form of hamartoma and benign tumors involving multiple organs and systems (Islam and Roach, 2015).
