MUTATION VERIFICATION |
Yang et al (Nature 310:412 1984) reported that northern blot analysis of RNA from this culture revealed a mutation that resulted in an aberrant HPRT mRNA of normal abundance that was approximately 250 nucleotides larger than wild-type HPRT mRNA. The mutation is a result of a duplication of exons 2 and 3 (Yang et al Somat Cell Mol Genet 14: 293 1988). |
|
hypoxanthine phosphoribosyltransferase |
According to the submitter, biochemical test results for this subject showed decreased enzyme activity. EC Number: 2.4.2.8; 0% activity. |

Identified Mutation |
EX2-3DUP, IVS1DEL; In GM1662 and GM6804 from patients with LNS, Yang et al.(1984, 1988) found a complex rearrangement involving duplication of exons 2 and 3 and deletion of intron 1. Increased size of mRNA was observed. Monnat et al. (1992) demonstrated that the duplication in GM6804 was generated by the nonhomologous insertion of duplicated HPRT DNA into HPRT intron 1. They found that the duplication was genetically unstable and had a reversion rate approximately 100-fold higher than the rate of duplication formation. Exons 2 and 3, together with 13.7 kb of surrounding HPRT sequence, were duplicated.

Remarks |
Clinically affected; no detectable HPRT and normal APRT activity; has an exon 2,3 duplication in the HPRT1 gene and a correspondingly elongated HPRT mRNA; atypical disease: lacks compulsive self-mutilation and mental retardation; see GM06804 for Lymph of same subject; mother (GM01659) and sisters (GM01660/GM01661) are unaffected carriers. |
