CFAP95
Chr 9cilia and flagella associated protein 95
Also known as: C9orf135
The CFAP95 protein is a microtubule inner protein component of dynein-decorated doublet microtubules in cilia axoneme that is required for motile cilia beating. Mutations cause primary ciliary dyskinesia, a disorder affecting the respiratory system, fertility, and organ positioning due to defective cilia motility. Primary ciliary dyskinesia follows autosomal recessive inheritance and typically presents in infancy or childhood with chronic respiratory symptoms.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Tolerant to missense variation
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.
