Genes affected

NDUFS6 (HGNC:7713): (NADH:ubiquinone oxidoreductase subunit S6) This gene encodes a subunit of the NADH:ubiquinone oxidoreductase (complex I), which is the first enzyme complex in the electron transport chain of mitochondria. This complex functions in the transfer of electrons from NADH to the respiratory chain. The subunit encoded by this gene is one of seven subunits in the iron-sulfur protein fraction. Mutations in this gene cause mitochondrial complex I deficiency, a disease that causes a wide variety of clinical disorders, including neonatal disease and adult-onset neurodegenerative disorders.[provided by RefSeq, Oct 2009]

This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 9 of the NDUFS6 protein (p.Arg9Pro). This variant is present in population databases (rs747196556, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with NDUFS6-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
