What causes Lesch-Nyhan syndrome What is the role of the enzyme that is lacking in individuals who have this disease?

Lesch-Nyhan syndrome (LNS) is a rare, inherited disorder caused by a deficiency of the enzyme hypoxanthine-guanine phosphoribosyltransferase (HPRT). LNS is an X-linked recessive disease– the gene is carried by the mother and passed on to her son. LNS is present at birth in baby boys.
