Lesch-Nyhan syndrome is a genetic disease, affecting almost solely males, of excessive synthesis of purines because of defective recycling and, therefore, uric acid production from their breakdown. Lesch-Nyhan syndrome is characterized by gouty ahritis but, in addition, affects the brain, resulting in mental retardation, loss of control of arm/leg/face movements, aggressive behavior, and self-mutilation by biting and scratching.
