Genes affected
DNAAF2 (HGNC:20188): (dynein axonemal assembly factor 2) This gene encodes a highly conserved protein involved in the preassembly of dynein arm complexes which power cilia. These complexes are found in some cilia and are assembled in the cytoplasm prior to transport for cilia formation. Mutations in this gene have been associated with primary ciliary dyskinesia. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Oct 2009]

Submissions by phenotype

Primary ciliary dyskinesia Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 12, 2017This sequence change creates a premature translational stop signal (p.Gln162*) in the DNAAF2 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 DNAAF2-related disease. Loss-of-function variants in DNAAF2 are known to be pathogenic (PMID: 19052621). For these reasons, this variant has been classified as Pathogenic. -
