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.344C>T (p.A115V) alteration is located in exon 3 (coding exon 3) of the UCKL1 gene. This alteration results from a C to T substitution at nucleotide position 344, causing the alanine (A) at amino acid position 115 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
