HGPRT deficiency

HGPRT deficiency

Deficiency of hypoxanthine-guanine-phosphor-ibosyl transferase. The absence of this enzyme occurs as the result of a rare X-linked recessive inheritance and leads to severe over-production of uric acid, spastic paralysis, ATHETOSIS, mental deficiency and a strong tendency to self-mutilation. Also known as LESCH-NYHAN SYNDROME.
