Genes affected

NUDT5 (HGNC:8052): (nudix hydrolase 5) This gene belongs to the Nudix (nucleoside diphosphate linked moiety X) hydrolase superfamily. The encoded enzyme catalyzes the hydrolysis of modified nucleoside diphosphates, including ADP-ribose (ADPR) and 8-oxoGua-containing 8-oxo-dADP and 8-oxo-dGDP. Protein-bound ADP ribose can be hazardous to the cell because it can modify some amino acid residues, resulting in the inhibition of ATP-activated potassium channels. 8-oxoGua is an oxidized form of guanine that can potentially alter genetic information by pairing with adenine and cytosine in RNA. Presence of 8-oxoGua in RNA results in formation of abnormal proteins due to translational errors. [provided by RefSeq, Aug 2013]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.137G>C (p.W46S) alteration is located in exon 4 (coding exon 3) of the NUDT5 gene. This alteration results from a G to C substitution at nucleotide position 137, causing the tryptophan (W) at amino acid position 46 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
