Genes affected

NOX4 (HGNC:7891): (NADPH oxidase 4) This gene encodes a member of the NOX-family of enzymes that functions as the catalytic subunit the NADPH oxidase complex. The encoded protein is localized to non-phagocytic cells where it acts as an oxygen sensor and catalyzes the reduction of molecular oxygen to various reactive oxygen species (ROS). The ROS generated by this protein have been implicated in numerous biological functions including signal transduction, cell differentiation and tumor cell growth. A pseudogene has been identified on the other arm of chromosome 11. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Jan 2009]

The c.858G>T (p.W286C) alteration is located in exon 10 (coding exon 10) of the NOX4 gene. This alteration results from a G to T substitution at nucleotide position 858, causing the tryptophan (W) at amino acid position 286 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
