Genes affected

CMPK2 (HGNC:27015): (cytidine/uridine monophosphate kinase 2) This gene encodes one of the enzymes in the nucleotide synthesis salvage pathway that may participate in terminal differentiation of monocytic cells. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2012]

The c.977C>T (p.P326L) alteration is located in exon 3 (coding exon 3) of the CMPK2 gene. This alteration results from a C to T substitution at nucleotide position 977, causing the proline (P) at amino acid position 326 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
