KIAA1191
Chr 5KIAA1191
Also known as: p33MONOX, p60MONOX
The protein is a mitochondrial NADPH-dependent oxidoreductase that may regulate neuronal survival, differentiation and axonal outgrowth. This gene is extremely intolerant to loss-of-function variants (pLI near 1.0), suggesting mutations would cause severe developmental disorders, though specific associated phenotypes have not yet been established. The inheritance pattern for pathogenic variants would be autosomal recessive or dominant depending on the specific mutation.
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 (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function 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.
