Genes affected
NDUFA12 (HGNC:23987): (NADH:ubiquinone oxidoreductase subunit A12) This gene encodes a protein which is part of mitochondrial complex 1, part of the oxidative phosphorylation system in mitochondria. Complex 1 transfers electrons to ubiquinone from NADH which establishes a proton gradient for the generation of ATP. Mutations in this gene are associated with Leigh syndrome due to mitochondrial complex 1 deficiency. Pseudogenes of this gene are located on chromosomes 5 and 13. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2012]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 04, 2022The c.403C>G (p.Q135E) alteration is located in exon 4 (coding exon 4) of the NDUFA12 gene. This alteration results from a C to G substitution at nucleotide position 403, causing the glutamine (Q) at amino acid position 135 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
