Summaries for PRPS1 Gene

Entrez Gene Summary for PRPS1 Gene

  • This gene encodes an enzyme that catalyzes the phosphoribosylation of ribose 5-phosphate to 5-phosphoribosyl-1-pyrophosphate, which is necessary for purine metabolism and nucleotide biosynthesis. Defects in this gene are a cause of phosphoribosylpyrophosphate synthetase superactivity, Charcot-Marie-Tooth disease X-linked recessive type 5 and Arts Syndrome. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2011]

PRPS1_HUMAN
  • Note=Phosphoribosyl pyrophosphate synthetase I deficiency is a rare condition caused by mutations in PRPS1 that lead to variable disease phenotypes including optic atrophy, retinitis pigmentosa, ataxia, peripheral neuropathy and hearing loss. {ECO:0000269 PubMed:25491489}.
  • Phosphoribosylpyrophosphate synthetase superactivity (PRPS1 superactivity) [MIM:300661]: Familial disorder characterized by excessive purine production, gout and uric acid urolithiasis. {ECO:0000269 PubMed:7593598, ECO:0000269 Ref.12}. Note=The disease is caused by variants affecting the gene represented in this entry.
  • Charcot-Marie-Tooth disease, X-linked recessive, 5 (CMTX5) [MIM:311070]: A form of Charcot-Marie-Tooth disease, a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies characterized by severely reduced motor nerve conduction velocities (NCVs) (less than 38m/s) and segmental demyelination and remyelination, and primary peripheral axonal neuropathies characterized by normal or mildly reduced NCVs and chronic axonal degeneration and regeneration on nerve biopsy. {ECO:0000269 PubMed:17701900}. Note=The disease is caused by variants affecting the gene represented in this entry.
  • ARTS syndrome (ARTS) [MIM:301835]: A disorder characterized by mental retardation, early-onset hypotonia, ataxia, delayed motor development, hearing impairment, and optic atrophy. Susceptibility to infections, especially of the upper respiratory tract, can result in early death. {ECO:0000269 PubMed:17701896}. Note=The disease is caused by variants affecting the gene represented in this entry.
  • Deafness, X-linked, 1 (DFNX1) [MIM:304500]: A form of deafness characterized by progressive, severe-to-profound sensorineural hearing loss in males. Females manifest mild to moderate hearing loss. {ECO:0000269 PubMed:20021999}. Note=The disease is caused by variants affecting the gene represented in this entry.
  • Note=A mutation in PRPS1 has been found in a patient with a phenotype that bridges that of PRSPS1 superactivity and ARTS syndrome with uric acid overproduction without gout but with recurrent infections, sensorineural hearing loss and motor neuropathy. The intermediate phenotype may be because Leu-142 variant affects both allosteric sites that are involved in inhibition of PRPS1 and the ATP-binding site, which suggests that this substitution can result both in a gain-of-function and loss-of-function of PRPP synthetase. {ECO:0000269 PubMed:22246954}.
