308000.0031; LESCH-NYHAN SYNDROME |
| Identified Mutation |
IVS7DS, G-A, +5; In cell line RJK1934 from a patient with LNS, Gibbs et al. (1990) found a GTAAGT-to-GTAAAT change at the beginning of intron 7. Interference with processing resulted from mutation in the donor splice site. See 308000.0029 for the corresponding mutation in intron 8.
|
| Remarks |
Clinically affected; onset of symptoms before age 1 year; motor delay at 3 months of age; limb posturing at 18 months; onset of self-injury at 4 years; hypotonia; dystonia; epileptic seizures; less than 1 percent of HPRT enzyme activity; physical and occupational therapy; psychological therapy; speech therapy; orthotics; donor subject is hemizygous for a G>A transition in intron 7 of the HPRT1 gene (IVS7+5G>A); affected brother is GM23785. |
