Hypoxanthine-guanine phosophoribosyltransferase (HPRT) deficiency: Lesch-Nyhan syndrome
Deficiency of hypoxanthine-guanine phosphoribosyltransferase (HPRT) activity is an inborn error of purine metabolism associated with uric acid overproduction and a continuum spectrum of neurological manifestations depending on the degree of the enzymatic deficiency. The prevalence is estimated at 1/380,000 live births in Canada, and 1/235,000 live births in Spain. Uric acid overproduction is pr...
متن کاملLesch-Nyhan Syndrome
Alternative names: Historically, Lesch-Nyhan syndrome is the designated term for this disease. Lesch-Nyhan Disease (LND) and hypoxanthine-guanine phosphoribosyl transferase (HPRT, HGprt) deficiency are also used to describe this disease. In addition to the classic form of LND, Jinnah and others have characterized two variant forms of the disorder -these individuals have higher levels of enzyme ...

متن کاملMicroRNA-mediated dysregulation of neural developmental genes in HPRT deficiency: clues for Lesch-Nyhan disease?
Mutations in the gene encoding the purine biosynthetic enzyme hypoxanthine-guanine phosphoribosyltransferase (HPRT) cause the intractable neurodevelopmental Lesch-Nyhan disease (LND) associated with aberrant development of brain dopamine pathways. In the current study, we have identified an increased expression of the microRNA miR181a in HPRT-deficient human dopaminergic SH-SY5Y neuroblastoma c...
متن کاملMolecular analysis of hypoxanthine guanine phosphoribosyltransferase (HPRT) gene in five Korean families with Lesch-Nyhan syndrome.
Lesch-Nyhan syndrome is caused by the complete deficiency of hypoxanthine guanine phosphoribosyl-transferase (HPRT). By the analysis of genomic DNA and mRNA using the polymerase chain reaction (PCR) technique coupled with direct sequencing, five independent mutations in HPRT genes have been identified in Korean Lesch-Nyhan families. Two novel mutations and three previously reported mutations ha...
