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 GeneticsOct 20, 2021The c.347T>C (p.I116T) alteration is located in exon 3 (coding exon 3) of the NDUFB4 gene. This alteration results from a T to C substitution at nucleotide position 347, causing the isoleucine (I) at amino acid position 116 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
