Genes affected

NDUFV3 (HGNC:7719): (NADH:ubiquinone oxidoreductase subunit V3) The protein encoded by this gene is one of at least forty-one subunits that make up the NADH-ubiquinone oxidoreductase complex. This complex is part of the mitochondrial respiratory chain and serves to catalyze the rotenone-sensitive oxidation of NADH and the reduction of ubiquinone. The encoded protein is one of three proteins found in the flavoprotein fraction of the complex. The specific function of the encoded protein is unknown. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.474C>A (p.S158R) alteration is located in exon 3 (coding exon 3) of the NDUFV3 gene. This alteration results from a C to A substitution at nucleotide position 474, causing the serine (S) at amino acid position 158 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
