Genes affected
NDUFB5 (HGNC:7700): (NADH:ubiquinone oxidoreductase subunit B5) The protein encoded by this gene is a subunit of the multisubunit NADH:ubiquinone oxidoreductase (complex I). Mammalian complex I is composed of 45 different subunits. It locates at the mitochondrial inner membrane. This protein has NADH dehydrogenase activity and oxidoreductase activity. It transfers electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 01, 2024The c.409A>G (p.M137V) alteration is located in exon 5 (coding exon 5) of the NDUFB5 gene. This alteration results from a A to G substitution at nucleotide position 409, causing the methionine (M) at amino acid position 137 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
