Genes affected

NQO2 (HGNC:7856): (N-ribosyldihydronicotinamide:quinone dehydrogenase 2) This gene encodes a member of the thioredoxin family of enzymes. It is a cytosolic and ubiquitously expressed flavoprotein that catalyzes the two-electron reduction of quinone substrates and uses dihydronicotinamide riboside as a reducing coenzyme. Mutations in this gene have been associated with neurodegenerative diseases and several cancers. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014]

Ambry Genetics

Dec 21, 2022

The c.29A>G (p.Y10C) alteration is located in exon 3 (coding exon 2) of the NQO2 gene. This alteration results from a A to G substitution at nucleotide position 29, causing the tyrosine (Y) at amino acid position 10 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
