Lesch Nyhan syndrome

Lesch-Nyhan syndrome (LNS) is an inherited recessive X-related disorder caused by the deficiency of the enzyme hypoxanthin-guanine phosphorribosyl transferase (HPRT). Compul sive self-mutilation and dystonia occurs before the first year of age and is expressed by persistent bites ...

Lesch-Nyhan syndrome (LNS) is an X-linked recessive disorder caused by a deficiency of hypoxanthine-guanine phosphoribosyltransferase (HPRT), an enzyme encoded by the HPRT1 gene. The classic disease phenotype described by Lesch and Nyhan in 1964 includes hyperuricemia, mental retardation, ...

Lesch-Nyhan syndrome (LNS) is a neurodevelopmental disorder caused by mutations in the gene encoding the purine metabolic enzyme hypoxanthine-guanine phosphoribosyltransferase (HPRT). A series of motor, cognitive and neurobehavioral anomalies characterize this disease phenotype, which ...

Deficiency of hypoxanthine phosphoribosyltransferase activity is a rare inborn error of purine metabolism with subsequent uric acid overproduction and neurologic presentations. The diagnosis of Lesch-Nyhan syndrome (LNS) is frequently delayed until self-mutilation becomes evident. ...

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 ...

We have reviewed the treatments employed to alleviate the different manifestations of the Lesch Nyhan syndrome, the adverse reactions related to these treatments, and the prospectives of future therapeutic approaches now under active research.
