| Identified Mutation |
GLN1503PRO; In a family with mild physical features of tuberous
sclerosis (191100) in association with neuropsychiatric disorders, Khare
et al. [J. Med. Genet. 38: 347-349 (2001)] reported an A-to-C transversion
at nucleotide 4508 in exon 34 of the TSC2 gene. This mutation resulted in
the substitution of a proline residue for a glutamine at codon 1503, which
Khare et al. [J. Med. Genet. 38: 347-349 (2001)] pointed out is within a
region with homology to rap1 GTPase-activating protein (600278). Khare et
al. [J. Med. Genet. 38: 347-349 (2001)] also found this mutation in an
unrelated family from the same geographic area. |
| Remarks |
Clinically affected half-brother of GM09432; hypomelanotic macules; renal cysts; member of a four generation family [family TS-15 in Smith et al. Genomics 6:105-114 (1990)] with 24 cases of tuberous sclerosis, some with only a mild form of the disease; donor subject carries a missense mutation in the GTPase activating protein homology region of the TSC2 gene due to an A-to-C transversion (CAG>CCG) at nucleotide position 4508 (4508A>C) which results in the substitution of proline for glutamine [GLN1503PRO (Q1503P)] at codon 1503 in exon 34 |
