Genes affected

GMPR (HGNC:4376): (guanosine monophosphate reductase) This gene encodes an enzyme that catalyzes the irreversible and NADPH-dependent reductive deamination of GMP to IMP. The protein also functions in the re-utilization of free intracellular bases and purine nucleosides.[provided by RefSeq, Oct 2009]

Ambry Genetics

Aug 10, 2021

The c.7C>G (p.R3G) alteration is located in exon 1 (coding exon 1) of the GMPR gene. This alteration results from a C to G substitution at nucleotide position 7, causing the arginine (R) at amino acid position 3 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
