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]

The c.382T>G (p.S128A) alteration is located in exon 4 (coding exon 4) of the NDUFA12 gene. This alteration results from a T to G substitution at nucleotide position 382, causing the serine (S) at amino acid position 128 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
