Genes affected
DNAAF5 (HGNC:26013): (dynein axonemal assembly factor 5) The protein encoded by this gene is essential for the preassembly or stability of axonemal dynein arms, and is found only in organisms with motile cilia and flagella. Mutations in this gene are associated with primary ciliary dyskinesia-18, a disorder characterized by abnormalities of motile cilia. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Feb 2013]

This sequence change creates a premature translational stop signal (p.Tyr782*) in the DNAAF5 gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with DNAAF5-related disease. ClinVar contains an entry for this variant (Variation ID: 454860). Loss-of-function variants in DNAAF5 are known to be pathogenic (PMID: 24307375, 25232951). For these reasons, this variant has been classified as Pathogenic. -
