December 2021; Orphanet Journal of Rare Diseases 16(1) DOI: 10.1186/s13023-020-01646-8. Children who inherit TSC may not have the same symptoms as their parent and they may have either a milder or a more severe form of the disorder. Loss of regulation of mTOR occurs in cells lacking either hamartin or tuberin, and this leads to abnormal differentiation and development, and to the generation of enlarged cells, as are seen in TSC brain lesions. The noncancerous tumors can grow in all parts of the body, but most commonly occur on the brain, kidneys, heart, lungs, eyes and skin. Many TSC patients show evidence of the disorder in the first year of life. … Cysts are usually small, appear in limited numbers, and cause no serious problems. Research studies run the gamut from very basic scientific investigation to clinical translational research. Tuberous Sclerosis Complex (TSC) is a genetic disorder that occurs in 1 out of 6,000 people and can involve multiple organs in the body, including the brain, heart, kidneys, lungs, eyes, and skin. Diagnosis of the disorder is based on a careful clinical exam in combination with computed tomography (CT) or magnetic resonance imaging (MRI) of the brain, which may show tubers in the brain, and an ultrasound of the heart, liver, and kidneys, which may show tumors in those organs. With appropriate medical care, most individuals with the disorder can look forward to normal life expectancy. Infantile spasms can occur as soon as the day of birth and are often difficult to recognize. It’s also the leading genetic cause of both epilepsy and autism.
