tu·ber·ous scle·ro·sis

phacomatosis characterized by the formation of multisystemic hamartomas producing seizures, mental retardation, and angiofibromas of the face; the cerebral and retinal lesions are glial nodules; other skin lesions are hypopigmented macules, shagreen patches, and periungual fibromas; autosomal dominant inheritance with variable expression, caused by mutation in either the tuberous sclerosis gene (TSC1) on chromosome 9q or TSC2 on 16p.

tuberous sclerosis type 1

An autosomal dominant multi-system disorder (OMIM:191100) characterised by hamartomas and developmental defects, which primarily affects the brain, kidneys, heart and skin.

Clinical findings
Range from benign hypopigmented skin macules, to profound mental retardation with intractable seizures and premature death due to disease-associated causes.
Molecular pathology
Defects of TSC1, which encodes a putative tumour suppressor, cause tuberous sclerosis type 1.
