Extractions: Resources Lesch-Nyhan syndrome is a rare genetic disorder that affects males. Males with this syndrome develop physical handicaps, mental retardation , and kidney problems. It is caused by a total absence of an enzyme. Self injury is a classic feature of this genetic disease. Lesch-Nyhan syndrome was first described in 1964 by Dr. Michael Lesch and Dr. William Nyhan. The syndrome is caused by a severe change (mutation) in the HPRT gene. This gene is responsible for the production the enzyme called hypoxanthine-guanine phosphoribosyltransferase(HPRT). HPRT catalyzes a reaction that is necessary to prevent the buildup of uric acid. A severe mutation in the HPRT gene leads to an absence of HPRT enzyme activity which, in turn, leads to markedly elevated uric acid levels in the blood(hyperuricemia). This buildup of uric acid is toxic to the body and is related to the symptoms associated with the disease. Absence of the HPRT enzyme activity is also thought to alter the chemistry of certain parts of the brain, such as the basal ganglia, affecting neurotransmitters (chemicals used for communication between nerve cells), acids, and other chemicals. This change in the nervous system is also related to the symptoms associated with Lesch-Nyhan syndrome. Males with Lesch-Nyhan syndrome develop neurologic problems during infancy. Infants with Lesch-Nyhan syndrome have weak muscle tone (hypotonia) and are unable to develop normally. Affected males develop uncontrollable writhing movements (athetosis) and muscle stiffness (spasticity) over time. Lack of speech is also a common feature of Lesch-Nyhan syndrome. The most dramatic symptom of Lesch-Nyhan syndrome is the compulsive self-injury seen in 85% of affected males. This self injury involves the biting of their own lips, tongue, and finger tips, as well as head banging. This behavior leads to serious injury and scarring.

http://www.whonamedit.com/synd.cfm/2175.html

Extractions: A rare and devastating genetic disorder of purine metabolism whereby hypoxanthine guanine phosphoribosyltransferase (HGPRT) results in overproduction of purine and consequently uric acid. Clinically the main characteristics are severe (usually) mental retardation, severely impaired growth, and tendency to self mutilation by lip, thumb, and foot biting; dislocation of eyes; face scratching; head banging. There are extrapyramidal signs with lack of coordination, aggressive behaviour, exaggerated tendon reflexes and positive Babinski signs. Epileptic seizures are present in about half the patients. Renal failure can occur before puberty. Patients are normal at birth but become irritable by 2-4 months. Self-destructive behaviour usually starts at 2 years of age. The disease almost exclusively affects males and is impossible to detect before delivery unless the mother is known to carry the gene. Etiology unknown. Sex-linked type of inheritance. Since the defective gene is recessive, females almost never exhibit the disease, but may be carriers. There are only two documented cases in females. Even distribution among races and geographic locales. Occurrence is approximately one in 380.000 births.

Extractions: Disease Injury Nutrition Poison ... Prevention Definition: Lesch-Nyhan syndrome is an inheritable disorder that affects purine metabolism . This affects how the body uses RNA and DNA, the proteins that make up the genetic blueprint and determine which proteins are produced for use in cellular processes. Males with Lesch-Nyhan have delayed motor development followed by bizarre, sinuous movements and increased deep tendon reflexes. A striking feature of Lesch-Nyhan syndrome is self-destructive behavior characterized by chewing off fingertips and lips, if not restrained. The excess uric acid levels cause children to develop gout-like swelling in some of their joints. In some cases, renal dysfunction develops because of the excess uric acid levels.
