Large deletion at the TSC1 locus in a family with tuberous sclerosis complex.
Tuberous sclerosis complex (TSC) is an autosomal dominant disorder characterized by seizures, mental retardation and the development of hamartomas in a variety of organs and tissues. The disease is caused by mutations in either the TSC1 gene on chromosome 9q34, or the TSC2 gene on chromosome 16p13.3. Here we describe a deletion encompassing the TSC1 gene and two neighboring transcripts on chromosome 9q34 in six affected individuals from a family with TSC. To our knowledge, this is the first report of such a large deletion at the TSC1 locus and indicates that screening for similar mutations at the TSC1 locus is warranted in individuals with TSC.
