Gene: HPRT1
Alternate names for this Gene: HGPRT|HPRT
Gene Summary: The protein encoded by this gene is a transferase, which catalyzes conversion of hypoxanthine to inosine monophosphate and guanine to guanosine monophosphate via transfer of the 5-phosphoribosyl group from 5-phosphoribosyl 1-pyrophosphate. This enzyme plays a central role in the generation of purine nucleotides through the purine salvage pathway. Mutations in this gene result in Lesch-Nyhan syndrome or gout.
Gene is located in Chromosome: X
Location in Chromosome : Xq26.2-q26.3
Description of this Gene: hypoxanthine phosphoribosyltransferase 1
