Purine Salvage Pathways phosphoribosyltransferase AMP + PPi Adenine + PRPP GMP + PPi Guanine + PRPP Lesch-Nyhan Syndrome -increasing levels of PRPP in patients (male children) suffering from Lesch-Nyhan Syndrome leads to increased de novo purine biosynthetic pathways -gout -brain dependent upon salvage pathways
