Genes affected

NDUFA9 (HGNC:7693): (NADH:ubiquinone oxidoreductase subunit A9) The encoded protein is a subunit of the hydrophobic protein fraction of the NADH:ubiquinone oxidoreductase (complex I), the first enzyme complex in the electron transport chain located in the inner mitochondrial membrane. A pseudogene has been identified on chromosome 12. [provided by RefSeq, May 2010]

ENSG00000255639 (HGNC:):
