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.1036G>A (p.V346I) alteration is located in exon 11 (coding exon 11) of the NOX4 gene. This alteration results from a G to A substitution at nucleotide position 1036, causing the valine (V) at amino acid position 346 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
