Genes affected

UCK2 (HGNC:12562): (uridine-cytidine kinase 2) This gene encodes a pyrimidine ribonucleoside kinase. The encoded protein (EC 2.7.1.48) catalyzes phosphorylation of uridine and cytidine to uridine monophosphate (UMP) and cytidine monophosphate (CMP), respectively.[provided by RefSeq, Oct 2010]

Jul 19, 2023

The c.652A>G (p.I218V) alteration is located in exon 7 (coding exon 7) of the UCK2 gene. This alteration results from a A to G substitution at nucleotide position 652, causing the isoleucine (I) at amino acid position 218 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
