A pathogenic mutation is defined as a mutation that clearly inactivates the function of the TSC1 or TSC2 proteins (e.g., out of frame insertion or deletion or nonsense mutation), prevents protein synthesis (e.g., large genomic deletion), or is a missense mutation whose effect on protein function has been established by functional assessment. 1992 Jan-Feb;13(1):295-7.

The finding of a sub-ependymal giant cell astrocytoma is sometimes seen in patients with tuberous sclerosis, and the finding of a subependymal hyperdense enhancing lesion is consistent with this diagnosis. Tuberous sclerosis complex (TSC) is a rare multisystem autosomal dominant genetic disease that causes non-cancerous tumours to grow in the brain and on other vital organs such as the kidneys, heart, liver, eyes, lungs and skin.A combination of symptoms may include seizures, intellectual disability, developmental delay, behavioral problems, skin abnormalities, lung disease, and kidney disease.

Other TSC1 or TSC2 variant… Healthcare professionals use a checklist of the characteristic features of tuberous sclerosis – such as abnormal areas of skin, or tumours in your eyes, brain, heart, lungs or kidneys – to confirm a diagnosis.  |  Some people with tuberous sclerosis have such mild signs and symptoms t… The CT findings in a patient with tuberous sclerosis are described with special emphasis upon the differential diagnosis. 1995 Jun;118 ( Pt 3):629-60. doi: 10.1093/brain/118.3.629. In some cases, cerebral cortical heterotopias are visualized as hypodense nonenhancing sub-ependymal lesions. Several tests will be needed to check for these features. Abnormalities of gyration, heterotopias, tuberous sclerosis, focal cortical dysplasia, microdysgenesis, dysembryoplastic neuroepithelial tumour and dysgenesis of the archicortex in epilepsy. The expression of the disease varies substantially. Gyriform calcifications in tuberous sclerosis simulating the appearance of Sturge-Weber disease. 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.

Tuberous sclerosis is found in 50% of cases of rabdomyoma (in the other 50% of cases the cardiac tumor is an isolated finding). Tuberous sclerosis was classically described as presenting in childhood with a triad (Vogt triad) of: 1. seizures: absent in one-quarter of individuals 2. intellectual disability: up to half have normal intelligence 3. adenoma sebaceum: only present in about three-quarters of patients1 The full triad is only seen in a minority of patients (~30%).

This is a rare autosomal dominant disorder with several skin lesions (fibrofolliculoma, trichodiscoma, and acrochordons) found on the face, which resemble the angiofibromas of TSC. Therefore, a negative genetic diagnostic test result does not exclude a diagnosis of tuberous sclerosis. Giant cell astrocytoma in tuberous sclerosis: computed tomographic findings. 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). 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. Tuberous sclerosis (also called tuberous sclerosis complex, or TSC) is a rare, multi-system genetic disease that causes non-cancerous (benign) tumors to grow in the brain and on other vital organs such as the kidneys, heart, eyes, lungs, and skin. The presence of multiple bilateral subependymal nodular nonenhancing hyperdense calcified lesions is relatively characteristic of tuberous sclerosis when combined with the appropriate clinical findings.
