Which of the following is not seen in tuberous sclerosis?
**Core Concept**
Tuberous sclerosis, also known as tuberous sclerosis complex (TSC), is a rare genetic disorder characterized by the growth of non-cancerous tumors in various parts of the body. It affects multiple organ systems, including the skin, brain, kidneys, and other organs.
**Why the Correct Answer is Right**
The correct answer is not explicitly given in the question, so I will provide a general explanation. Tuberous sclerosis is associated with the development of various types of tumors, including angiofibromas, subependymal giant cell astrocytomas (SEGAs), renal angiomyolipomas, and lymphangiomyomas. These tumors are a hallmark of the disease and are caused by mutations in the TSC1 or TSC2 genes, which regulate the mTOR pathway.
