They occur in the cerebellum as well, where they may be apparent only on microscopic examination. Gastrointestinal involvement in tuberous sclerosis. Tuberous sclerosis, otherwise referred to as Bourneville's disease or tuberous sclerosis complex, is an inherited disease that affects multiple systems. TSC patients with extensive renal cysts may occasionally be misdiagnosed as having polycystic kidney disease. Tuberous sclerosis is a genetic disease characterized by nonmalignant tumor growth in all organs due to the inactivation of tumor growth suppressors. Tumours that develop in the brain can potentially cause a range of problems. If such a pathogenic mutation is found then this alone is sufficient to diagnose TSC. In many cases, these cysts and tumours do not cause a problem. These usually develop during the first year of life. What are major features of tuberous sclerosis complex (TSC)? Tuberous sclerosis is an autosomal dominant neurocutaneous syndrome characterized by various abnormalities, including multisystemic hamartomas. Hizawa K, Iida M, Matsumoto T, et al. 2013.

Medically Reviewed by a doctor on 20 May 2016. However, some mutations are less clear in their effect, and so not sufficient alone for diagnosis. In other places in your body, you may have patches of different color skin and dark or light growths that might look like warts. However, in a small number of cases, the tumours can cause problems such as an irregular heart beat(arrhythmia) or heart failure . Patients with tuberous sclerosis complex, a genetic disorder characterized by the growth of noncancerous tumors in multiple organs of the body, have limited treatment options. Tuberous sclerosis has a significant number of manifestations, involving many organ systems. There are many different mutations in the TSC1 and TSC2 genes that have been identified in individuals with TSC. Tuberous sclerosis is a genetic disease characterized by nonmalignant tumor growth in all organs due to the inactivation of tumor growth suppressors.
