Lesch-Nyhan syndrome is a problem that occurs practically exclusively in males. Excess uric acid can be released from the blood and accumulate under the skin and cause gouty arthritis. Uric acid build-up can cause kidney and bladder rocks. The nerve system and behavioral disturbances experienced by people with Lesch-Nyhan syndrome consist of abnormal involuntary muscular tissue motions, such as tensing of different muscles, jerking activities, and flailing of the limbs. People with Lesch-Nyhan syndrome usually can not walk, require assistance resting, and normally use a mobility device. Self-injury is one of the most common and distinctive behavior problem in people with Lesch-Nyhan syndrome. Purines are a normal part of human tissue that help compose the body's hereditary plan. People with this syndrome are missing out on or badly lacking an enzyme called hypoxanthine guanine phosphoribosyltransferase. Without it, abnormally high degrees of uric acid develop in the body. Too much uric acid can cause gout-like swelling in several of the joints. In some cases, kidney and bladder rocks develop. People with Lesch-Nyhan have delayed motor advancement followed by abnormal movements and increased reflexes. A striking feature of Lesch-Nyhan syndrome is suicidal behavior, including eating off fingertips and lips. Uric acid degrees are abnormally high in people with Lesch-Nyhan syndrome and sodium urate crystals might unusually accumulate in the kidneys and joints. Urate crystals might also be found in the joints, yet generally, it is not up until the late teenagers or their adult years that untreated patients with Lesch-Nyhan syndrome experience recurring episodes of pain and swelling of the joints, much like those of adults with gout pain. Ultimately, most children with Lesch-Nyhan syndrome experience abnormally increased muscular tissue tone and muscular tissue strength.
