Genes affected

UCKL1 (HGNC:15938): (uridine-cytidine kinase 1 like 1) The protein encoded by this gene is a uridine kinase. Uridine kinases catalyze the phosphorylation of uridine to uridine monophosphate. This protein has been shown to bind to Epstein-Barr nuclear antigen 3 as well as natural killer lytic-associated molecule. Ubiquitination of this protein is enhanced by the presence of natural killer lytic-associated molecule. In addition, protein levels decrease in the presence of natural killer lytic-associated molecule, suggesting that association with natural killer lytic-associated molecule results in ubiquitination and subsequent degradation of this protein. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2014]

The c.736G>A (p.G246S) alteration is located in exon 6 (coding exon 6) of the UCKL1 gene. This alteration results from a G to A substitution at nucleotide position 736, causing the glycine (G) at amino acid position 246 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
