Comment on list classification: This gene was part of an initial gene list collated by Emma Ashton on behalf of the London North GLH, for GMS Metabolic Consensus Specialist Test Group. Additional information was not provided, such as mode of inheritance and phenotype.
Associated with relevant phenotype in OMIM and as confirmed Gen2Phen gene for Arts syndrome 301835, Charcot-Marie-Tooth disease, X-linked recessive, 5 311070, Deafness, X-linked 1 304500 and Phosphoribosylpyrophosphate synthetase superactivity 300661. At least 22 variants have been reported across the phenotypes.Created: 22 Aug 2019, 2:27 p.m. | Last Modified: 22 Aug 2019, 2:27 p.m.

Phenotypes for gene: PRPS1 were changed from Intellectual disability; Charcot-Marie-Tooth disease; Phosphoribosyl pyrophosphate synthetase 1 defects (Disorders of purine metabolism); Congenital hearing impairment (profound/severe); Intellectual_disability to Arts syndrome 301835; Charcot-Marie-Tooth disease, X-linked recessive, 5 311070; Deafness, X-linked 1 304500; Gout, PRPS-related 300661; Phosphoribosylpyrophosphate synthetase superactivity 300661
Gene: prps1 has been classified as Green List (High Evidence).
Mode of inheritance for gene: PRPS1 was changed from X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males) to X-LINKED: hemizygous mutation in males, biallelic mutations in females
