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 replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 268 of the DNAAF5 protein (p.Val268Met). This variant is present in population databases (rs370267615, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with DNAAF5-related conditions. ClinVar contains an entry for this variant (Variation ID: 579022). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt DNAAF5 protein function. 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. -
