NDUFA1
Chr XXLRNADH:ubiquinone oxidoreductase subunit A1
This protein is an essential component of mitochondrial respiratory complex I that transfers electrons from NADH to ubiquinone and anchors the complex to the inner mitochondrial membrane. Mutations cause mitochondrial complex I deficiency, nuclear type 12, which follows X-linked recessive inheritance. The pathogenic mechanism involves dominant-negative effects where mutant proteins disrupt normal complex I assembly and function.

Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Mild missense constraint
This gene has evidence for multiple mechanisms of pathogenicity (dominant-negative and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to dominant-negative as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.
Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
