Summaries for HPRT1 Gene

Entrez Gene Summary for HPRT1 Gene

  • 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.[provided by RefSeq, Jun 2009]

GeneCards Summary for HPRT1 Gene

HPRT1 (Hypoxanthine Phosphoribosyltransferase 1) is a Protein Coding gene. Diseases associated with HPRT1 include Lesch-Nyhan Syndrome and Hprt-Related Gout. Among its related pathways are Purine metabolism and Metabolism. GO annotations related to this gene include protein homodimerization activity and nucleotide binding. An important paralog of this gene is PRTFDC1.
