Genes affected

ODAD3 (HGNC:28303): (outer dynein arm docking complex subunit 3) This gene encodes a protein containing coiled-coil domains. The encoded protein functions in outer dynein arm assembly and is required for motile cilia function. Mutations in this gene result in primary ciliary dyskinesia. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Oct 2014]

This variant has not been reported in the literature in individuals affected with CCDC151-related conditions. This variant, c.1695_1697del, results in the deletion of 1 amino acid(s) of the CCDC151 protein (p.Glu565del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs771032462, gnomAD 0.02%). 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. -
