Genes affected
GMPR2 (HGNC:4377): (guanosine monophosphate reductase 2) This gene encodes an enzyme that catalyzes the irreversible and NADPH-dependent reductive deamination of guanosine monophosphate (GMP) to inosine monophosphate (IMP). The protein also functions in the re-utilization of free intracellular bases and purine nucleosides. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2017]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 26, 2024The c.178A>G (p.K60E) alteration is located in exon 2 (coding exon 2) of the GMPR2 gene. This alteration results from a A to G substitution at nucleotide position 178, causing the lysine (K) at amino acid position 60 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
