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 GeneticsApr 11, 2023The c.56C>T (p.P19L) alteration is located in exon 1 (coding exon 1) of the GMPR gene. This alteration results from a C to T substitution at nucleotide position 56, causing the proline (P) at amino acid position 19 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
