Abstract
Tuberous sclerosis complex (TSC) is an autosomal dominant syndrome in which patients develop hamartomatous lesions in the nervous system and a host of other organs. While considerable experience has been gained in defining the clinical spectrum of TSC, a number of nosological questions remain. Neuropathological studies have continued to refine our knowledge of the nervous system abnormalities that characterize TSC. Molecular genetic studies have implicated two chromosomal regions in the genesis of TSC, one on chromosome 9q and the other on chromosome 16p. The chromosome 16p gene, designated TSC2, has been cloned, although its function remains speculative. The identification of the TSC1 gene on chromosome 9q, along with functional studies and mutational analyses of both TSC genes, will likely provide fascinating insights into the pathogenesis of TSC.
