Primary ciliary dyskinesia Uncertain:3
This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 4582 of the DNAH5 protein (p.Tyr4582Cys). This variant is present in population databases (rs749862482, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with DNAH5-related conditions. ClinVar contains an entry for this variant (Variation ID: 525409). 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) has been performed at Invitae 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 DNAH5 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. -

The p.Y4582C variant (also known as c.13745A>G), located in coding exon 79 of the DNAH5 gene, results from an A to G substitution at nucleotide position 13745. The tyrosine at codon 4582 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. 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. -
