Genes affected
PRPS1 (HGNC:9462): (phosphoribosyl pyrophosphate synthetase 1) 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]

ACMG classification
Classification made for transcript
Verdict is Likely_pathogenic. Variant got 7 ACMG points.
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), PRPS1. . Gene score misZ: 3.7321 (greater than the threshold 3.09). The gene has 32 curated pathogenic missense variants (we use a threshold of 10). The gene has 18 curated benign missense variants. GenCC has associacion of the gene with severe phosphoribosylpyrophosphate synthetase superactivity, Arts syndrome, PRPS1 deficiency disorder, X-linked intellectual disability-limb spasticity-retinal dystrophy-diabetes insipidus syndrome, mild phosphoribosylpyrophosphate synthetase superactivity, Charcot-Marie-Tooth disease X-linked recessive 5, phosphoribosylpyrophosphate synthetase superactivity, X-linked nonsyndromic hearing loss, hearing loss, X-linked 1.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.882
PP5
Variant X-107650000-G-T is Pathogenic according to our data. Variant chrX-107650000-G-T is described in ClinVar as [Pathogenic]. Clinvar id is 140573.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chrX-107650000-G-T is described in Lovd as [Pathogenic].
