Uric Acid 46-55 phosphoribosyl pyrophosphate synthetase 1 Homo sapiens 14-19 30423175-1 2018 Objectives: Phosphoribosylpyrophosphate synthetase (PRPS1) superactivity is an X-linked disorder characterized by urate overproduction Online Mendelian Inheritance in Man (OMIM) gene reference 300661. Uric Acid 114-119 phosphoribosyl pyrophosphate synthetase 1 Homo sapiens 52-57 30423175-9 2018 Conclusion: Clinical findings in previously reported females with PRPS1 superactivity showed a high clinical penetrance of this disorder with a mean serum urate level of 8.5 (4.1) mg/dl [506 (247) mumol/l] and a high prevalence of gout. Uric Acid 155-160 phosphoribosyl pyrophosphate synthetase 1 Homo sapiens 66-71 22246954-1 2012 We identified a novel missense mutation, c.424G>C (p.Val142Leu) in PRPS1 in a patient with uric acid overproduction without gout but with developmental delay, hypotonia, hearing loss, and recurrent respiratory infections. Uric Acid 94-103 phosphoribosyl pyrophosphate synthetase 1 Homo sapiens 70-75 22246954-7 2012 Our results show that missense mutations in PRPS1 can cause a continuous spectrum of features ranging from progressive non-syndromic postlingual hearing impairment to uric acid overproduction, neuropathy, and recurrent infections depending on the functional sites that are affected. Uric Acid 167-176 phosphoribosyl pyrophosphate synthetase 1 Homo sapiens 44-49 20380929-5 2010 Patients with PRS-I superactivity primarily present with uric acid overproduction, mental retardation, ataxia, hypotonia, and hearing impairment. Uric Acid 57-66 phosphoribosyl pyrophosphate synthetase 1 Homo sapiens 14-19 17701896-7 2007 The loss-of-function mutations of PRPS1 likely result in impaired purine biosynthesis, which is supported by the undetectable hypoxanthine in urine and the reduced uric acid levels in serum from patients. Uric Acid 164-173 phosphoribosyl pyrophosphate synthetase 1 Homo sapiens 34-39 12847698-3 2003 Results of enzymatic and genetic studies supported the view that accelerated purine nucleotide and uric acid production in this woman resulted from defective allosteric regulation of PRS activity, which is, in turn, a consequence of a mutation in one of the patient"s PRPS1 genes: an A-to-T substitution at nucleotide 578, encoding leucine for histidine at amino acid residue 192 of the mature PRS1 isoform. Uric Acid 99-108 phosphoribosyl pyrophosphate synthetase 1 Homo sapiens 268-273
