Genes affected
NDUFA8 (HGNC:7692): (NADH:ubiquinone oxidoreductase subunit A8) The protein encoded by this gene belongs to the complex I 19 kDa subunit family. Mammalian complex I is composed of 45 different subunits. This protein has NADH dehydrogenase activity and oxidoreductase activity. It plays an important role in transfering electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone. Alternative splicing of this gene results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2015]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2022The c.229C>G (p.H77D) alteration is located in exon 3 (coding exon 3) of the NDUFA8 gene. This alteration results from a C to G substitution at nucleotide position 229, causing the histidine (H) at amino acid position 77 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
