Welcome to TSCLife Tuberous sclerosis complex (TSC) is a lifelong disease that causes various complications in different parts of the body, including noncancerous tumors and seizures.Living with TSC can be challenging. The presence of pulmonary lymphangioleiomyomatosis, multifocal micronodular pneumocyte hyperplasia, or multiple renal cysts also raises suspicion of tuberous sclerosis.

Tumors in a kidney can stop it from working like it should. This manifestation involves the contiguous deletion of a portion of the adjacent TSC2 and PKD1 genes on chromosome 16p13, and accounts for about 2% of TSC patients. Renal cysts in this form of TSC arise from all nephron segments. (See "Tuberous sclerosis complex: Genetics, clinical features, and diagnosis", section on 'Genetics'.).
