Genes affected

UCK1 (HGNC:14859): (uridine-cytidine kinase 1) This gene encodes a uridine-cytidine kinase that catalyzes the phosphorylation of uridine and cytidine to uridine monophosphate (UMP) and cytidine monophosphate (CMP) but not the phosphorylation of deoxyribonucleosides or purine ribonucleosides. This enzyme can also phosphorylate uridine and cytidine analogs and uses both ATP and GTP as a phosphate donor. Alternative splicing results in multiple splice variants encoding distinct isoforms.

The c.809T>C (p.L270S) alteration is located in exon 7 (coding exon 7) of the UCK1 gene. This alteration results from a T to C substitution at nucleotide position 809, causing the leucine (L) at amino acid position 270 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
