Lesch Nyhan syndrome is an inherited condition caused by the build-up of uric acid.[1] Excess uric acid can cause sodium urate crystals to form in the joints, kidneys, central nervous system, and other tissues of the body.[2] Symptoms may include arthritis, poor muscle control, moderate cognitive disabilities, severe kidney problems, and self-mutilating behaviors.[1][2] Lesch Nyhan syndrome is caused by mutations in the HPRT1 gene. It is inherited in an X-linked recessive manner.[1] Treatment is based on the symptoms.[2]
