Primary ciliary dyskinesia Uncertain:2
The p.R277H variant (also known as c.830G>A), located in coding exon 3 of the DNAAF5 gene, results from a G to A substitution at nucleotide position 830. The arginine at codon 277 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. 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 histidine, which is basic and polar, at codon 277 of the DNAAF5 protein (p.Arg277His). This variant is present in population databases (rs760388668, gnomAD 0.01%). This missense change has been observed in individual(s) with clinical features of primary ciliary dyskinesia (internal data). ClinVar contains an entry for this variant (Variation ID: 525442). 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) indicates that this missense variant is expected to disrupt DNAAF5 protein function with a positive predictive value of 80%. 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. -
