Genes affected

NOX3 (HGNC:7890): (NADPH oxidase 3) This gene encodes a member of the NOX family of NADPH oxidases. These enzymes have the capacity to generate superoxide and other reactive oxygen species (ROS) and transport electrons across the plasma membrane. The ROS generated by family members have been implicated in numerous biological functions including host defense, posttranlational processing of proteins, cellular signaling, regulation of gene expression, and cell differentiation. The protein encoded by this gene is expressed predominantly in the inner ear and is involved in the biogenesis of otoconia/otolith, which are crystalline structures of the inner ear involved in the perception of gravity.[provided by RefSeq, May 2009]

The c.775C>A (p.Q259K) alteration is located in exon 7 (coding exon 7) of the NOX3 gene. This alteration results from a C to A substitution at nucleotide position 775, causing the glutamine (Q) at amino acid position 259 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
