NDUFA10
Chr 2ARNADH:ubiquinone oxidoreductase subunit A10
Also known as: CI-42KD, CI-42k, MC1DN22
The encoded protein is a subunit of mitochondrial complex I that functions as an NADH dehydrogenase, transferring electrons from NADH to the respiratory chain in oxidative phosphorylation. Mutations cause mitochondrial complex I deficiency, nuclear type 22, which can present as Leigh syndrome, inherited in an autosomal recessive pattern. The pathogenic mechanism involves loss of function leading to impaired mitochondrial energy production.
Primary Disease Associations & Inheritance

Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Tolerant to missense variation
Predictions shown for reference only — model trained on dominant genes, not applicable to AR conditions.
The Badonyi & Marsh prediction model was trained exclusively on dominant disease genes. Predictions are not reliable for genes with autosomal recessive inheritance and are shown at reduced opacity for reference only.
