Genes affected

NDUFB6 (HGNC:7701): (NADH:ubiquinone oxidoreductase subunit B6) 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. Alternative splicing occurs at this locus and three transcript variants encoding distinct isoforms have been identified. [provided by RefSeq, Jan 2011]

Ambry Genetics

Nov 17, 2022

The c.316C>T (p.P106S) alteration is located in exon 3 (coding exon 3) of the NDUFB6 gene. This alteration results from a C to T substitution at nucleotide position 316, causing the proline (P) at amino acid position 106 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
