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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 13, 2021The c.437G>A (p.R146H) alteration is located in exon 4 (coding exon 4) of the GMPR gene. This alteration results from a G to A substitution at nucleotide position 437, causing the arginine (R) at amino acid position 146 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
