Genes affected
CMPK1 (HGNC:18170): (cytidine/uridine monophosphate kinase 1) This gene encodes one of the enzymes required for cellular nucleic acid biosynthesis. This enzyme catalyzes the transfer of a phosphate group from ATP to CMP, UMP, or dCMP, to form the corresponding diphosphate nucleotide. Alternate splicing results in both coding and non-coding transcript variants. [provided by RefSeq, Feb 2012]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 19, 2024The c.385G>A (p.E129K) alteration is located in exon 3 (coding exon 3) of the CMPK1 gene. This alteration results from a G to A substitution at nucleotide position 385, causing the glutamic acid (E) at amino acid position 129 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
