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

Sep 01, 2021

The c.196G>A (p.V66M) alteration is located in exon 2 (coding exon 2) of the GMPR gene. This alteration results from a G to A substitution at nucleotide position 196, causing the valine (V) at amino acid position 66 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
