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]

The c.617C>T (p.T206I) alteration is located in exon 6 (coding exon 6) of the GMPR2 gene. This alteration results from a C to T substitution at nucleotide position 617, causing the threonine (T) at amino acid position 206 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
