Genes affected
NDUFB4 (HGNC:7699): (NADH:ubiquinone oxidoreductase subunit B4) This gene encodes a non-catalytic subunit of the multisubunit NADH:ubiquinone oxidoreductase, the first enzyme complex in the mitochondrial electron transport chain (complex I). Mammalian complex I is composed of 45 different subunits and transfers electrons from NADH to ubiquinone. [provided by RefSeq, Dec 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2023The c.15G>C (p.K5N) alteration is located in exon 1 (coding exon 1) of the NDUFB4 gene. This alteration results from a G to C substitution at nucleotide position 15, causing the lysine (K) at amino acid position 5 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
