Genes affected
NDUFB3 (HGNC:7698): (NADH:ubiquinone oxidoreductase subunit B3) This gene encodes an accessory subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) which is the first enzyme in the electron transport chain of mitochondria. This protein localizes to the inner membrane of the mitochondrion as a single-pass membrane protein. Mutations in this gene contribute to mitochondrial complex 1 deficiency. Alternative splicing results in multiple transcript variants encoding the same protein. Humans have multiple pseudogenes of this gene. [provided by RefSeq, Mar 2012]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 09, 2022The c.96C>G (p.I32M) alteration is located in exon 2 (coding exon 1) of the NDUFB3 gene. This alteration results from a C to G substitution at nucleotide position 96, causing the isoleucine (I) at amino acid position 32 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
