Genes affected
CCDC39 (HGNC:25244): (coiled-coil domain 39 molecular ruler complex subunit) The protein encoded by this gene is involved in the motility of cilia and flagella. The encoded protein is essential for the assembly of dynein regulatory and inner dynein arm complexes, which regulate ciliary beat. Defects in this gene are a cause of primary ciliary dyskinesia type 14 (CILD14). [provided by RefSeq, Jul 2011]

Primary ciliary dyskinesia Uncertain:1
Jun 04, 2022
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant, c.67_69del, results in the deletion of 1 amino acid(s) of the CCDC39 protein (p.Glu23del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs771715698, gnomAD 0.005%). This variant has not been reported in the literature in individuals affected with CCDC39-related conditions. ClinVar contains an entry for this variant (Variation ID: 525369). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
