What is Lesch-Nyhan Syndrome?
This devastating disease results in abnormal motor development that often resembles cerebral palsy, severe mental retardation, and a compulsion to engage in self-injurious behavior. Lesch-Nyhan syndrome (LNS) is an inherited, metabolic disorder characterized by an almost complete absence of the enzyme, hypoxanthine-guanine phosphoribosyltransferase (HPRT) , which is responsible for the metabolism of purine. It is found only in males and is recognized by the excessive production of uric acid and several neurological conditions, including motor abnormalities and self-mutilation.
