Six families with mosaicism are identified in a series of 62 unrelated families with a mutation in one of the two tuberous sclerosis complex (TSC) genes, TSC1 or TSC2. In five families, somatic mosaicism was present in a mildly affected parent of an index patient. In one family with clinically unaffected parents, gonadal mosaicism was detected after TSC was(More)
For four of the most well-known craniosynostosis syndromes--Apert's, Crouzon's, Pfeiffer's, and Jackson-Weiss' syndromes--mutations in the fibroblast growth factor receptors (FGFRs) have been described. These substitutions arise mainly in the FGFR-2 gene and to a much lesser degree in the FGFR-1 and FGFR-3 genes. We present a patient with an apparently(More)
Important symptoms of tuberous sclerosis complex (TSC), an autosomal dominant disorder, are hamartomata in several organs, mental retardation and epilepsy. Either one of two loci can be involved (TSC1 and TSC2), of which the TSC2 gene has been cloned. To date, only 35 mutations in the TSC2 gene have been described ranging from large deletions to point(More)
We describe three members each of two families presenting with a hereditary form of lower motor neuron disease with adult onset and rapid progression and compare their pathological and clinical features with hereditary lower motor neuron disease with adult onset, as described in the literature. No involvement of upper motor neurons was found either(More)
