Primary ciliary dyskinesia Uncertain:2
The p.R496W variant (also known as c.1486C>T), located in coding exon 12 of the DNAAF3 gene, results from a C to T substitution at nucleotide position 1486. The arginine at codon 496 is replaced by tryptophan, an amino acid with dissimilar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 496 of the DNAAF3 protein (p.Arg496Trp). This variant is present in population databases (rs77322382, gnomAD 0.08%). This variant has not been reported in the literature in individuals affected with DNAAF3-related conditions. ClinVar contains an entry for this variant (Variation ID: 582989). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on DNAAF3 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. -
