Abstract
- Lesch-Nyhan disease is a very rare X-linked recessive disorder characterized by mental retardation, spasticity resembling cerebral palsy, choreoathetosis, self-mutilation and hyperuricemia. Self-mutilative behavior is a hallmark of the disease. The underlying defect is a deficiency of hypoxanthine-guanine phosphoribosyltransferase (HPRT). We report on a fourteen-year-old boy, who manifested gouty arthritis and mild renal insufficiency with Lesch-Nyhan disease, lacking self-mutilative behavior in spite of undetectable HPRT activity. Though there were several reports about some cases of Lesch-Nyhan disease in the past Korean literature, the cases were classic forms with definite neurological manifestation. As far as we know, this is the first case of Lesch-Nyhan disease without self-mutilation in Korea.
