[https://www.uniprot.org/uniprot/HPRT_HUMAN HPRT_HUMAN] Defects in HPRT1 are the cause of Lesch-Nyhan syndrome (LNS) [MIM:[https://omim.org/entry/300322 300322]. LNS is characterized by complete lack of enzymatic activity that results in hyperuricemia, choreoathetosis, mental retardation, and compulsive self-mutilation.<ref>PMID:6853716</ref> <ref>PMID:3384338</ref> <ref>PMID:3265398</ref> <ref>PMID:2910902</ref> <ref>PMID:2347587</ref> <ref>PMID:2358296</ref> <ref>PMID:2246854</ref> <ref>PMID:2071157</ref> <ref>PMID:7627191</ref> <ref>PMID:9452051</ref> Defects in HPRT1 are the cause of gout HPRT-related (GOUT-HPRT) [MIM:[https://omim.org/entry/300323 300323]; also known as HPRT-related gout or Kelley-Seegmiller syndrome. Gout is characterized by partial enzyme activity and hyperuricemia.<ref>PMID:6853490</ref> <ref>PMID:6572373</ref> <ref>PMID:6706936</ref> <ref>PMID:3358423</ref> <ref>PMID:3198771</ref> <ref>PMID:2909537</ref> [:]

== Function ==
 +
[https://www.uniprot.org/uniprot/HPRT_HUMAN HPRT_HUMAN] Converts guanine to guanosine monophosphate, and hypoxanthine to inosine monophosphate. Transfers the 5-phosphoribosyl group from 5-phosphoribosylpyrophosphate onto the purine. Plays a central role in the generation of purine nucleotides through the purine salvage pathway.
