CFAP119

Chr 16

cilia and flagella associated protein 119

Also known as: C16orf93, CCDC189

CFAP119 encodes a protein predicted to function in sperm flagellum assembly and is part of the radial spoke structure within the axoneme. Mutations cause primary ciliary dyskinesia with or without situs inversus, an autosomal recessive disorder affecting respiratory function and ciliary motility. The gene shows minimal constraint against loss-of-function variants, consistent with its recessive inheritance pattern.

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.
