Genes affected

NOXA1 (HGNC:10668): (NADPH oxidase activator 1) This gene encodes a protein which activates NADPH oxidases, enzymes which catalyze a reaction generating reactive oxygen species. The encoded protein contains four N-terminal tetratricopeptide domains and a C-terminal Src homology 3 domain. Interaction between the encoded protein and proteins in the oxidase regulatory complex occur via the tetratricopeptide domains. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

Collection Method: clinical testing

The c.553C>T (p.R185W) alteration is located in exon 5 (coding exon 5) of the NOXA1 gene. This alteration results from a C to T substitution at nucleotide position 553, causing the arginine (R) at amino acid position 185 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
