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]

Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jan 28, 2022 | For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with NDUFAF5-related conditions. This variant is present in population databases (rs763023951, gnomAD 0.005%). This sequence change creates a premature translational stop signal (p.Trp8*) in the NDUFAF5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in NDUFAF5 are known to be pathogenic (PMID: 26275793, 30473481, 32918965). - |
