Genes affected

NDUFAF5 (HGNC:15899): (NADH:ubiquinone oxidoreductase complex assembly factor 5) The NADH-ubiquinone oxidoreductase complex (complex I) of the mitochondrial respiratory chain catalyzes the transfer of electrons from NADH to ubiquinone, and consists of at least 43 subunits. The complex is located in the inner mitochondrial membrane. This gene encodes a mitochondrial protein that is associated with the matrix face of the mitochondrial inner membrane and is required for complex I assembly. A mutation in this gene results in mitochondrial complex I deficiency. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2009]

This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 229 of the NDUFAF5 protein (p.Leu229Pro). This variant is present in population databases (rs118203929, gnomAD 0.02%). This missense change has been observed in individual(s) with mitochondrial complex I deficiency (PMID: 18940309). It has also been observed to segregate with disease in related individuals. This variant is also known as c.719T>C, p.Leu229Pro in literature. ClinVar contains an entry for this variant (Variation ID: 570). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt NDUFAF5 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects NDUFAF5 function (PMID: 18940309, 23536703). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
