When patients do not meet these criteri… 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. Comparisons may be useful for a differential diagnosis: The various symptoms of tuberous sclerosis are nonspecific and many can occur as isolated findings or as part of another syndrome or disorder. This site needs JavaScript to work properly. 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.

Raymond AA, Fish DR, Sisodiya SM, Alsanjari N, Stevens JM, Shorvon SD. Tuberous sclerosis complex (TSC) is an autosomal-dominant, neurocutaneous, multisystem disorder characterized by cellular hyperplasia, tissue dysplasia, and multiple organ hamartomas. 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). Angiomyolipomas are the most common benign solid renal lesion and also the most common fat-containing lesion of the kidneys. 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. | Differential diagnosis, Diagnosis, Vitiligo, CKS. The majority of angiomyolipomas are sporadic (80%) and are typically identified in adults (mean age of presentation 43 years), with a female predilection (F:M of 2-4:1) 7,9. 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%).
