RCV000539548 | SCV000624329 | pathogenic | Primary ciliary dyskinesia | 2024-01-31 | criteria provided, single submitter | clinical testing | This sequence change replaces tryptophan, which is neutral and slightly polar, with serine, which is neutral and polar, at codon 568 of the DNAI1 protein (p.Trp568Ser). This variant is present in population databases (rs772686744, gnomAD 0.004%). This missense change has been observed in individual(s) with primary ciliary dyskinesia (PMID: 11713099, 18434704; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 288744). 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 DNAI1 protein function with a positive predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. |
| Ambry Genetics | RCV000539548 | SCV002715790 | likely pathogenic | Primary ciliary dyskinesia | 2018-01-29 | criteria provided, single submitter | clinical testing | The p.W568S variant (also known as c.1703G>C), located in coding exon 17 of the DNAI1 gene, results from a G to C substitution at nucleotide position 1703. The tryptophan at codon 568 is replaced by serine, an amino acid with highly dissimilar properties. This variant was first described in two siblings with respiratory distress syndrome, outer dynein arm defects on electron microscopy, and a second pathogenic alteration confirmed in trans; one of the siblings also had situs inversus (Zariwala M et al. Am. J. Respir. Cell Mol. Biol., 2001 Nov;25:577-83). This variant was also detected in another individual with a clinical diagnosis of primary ciliary dyskinesia with outer arm defects on electron microscopy, in compound heterozygous state with a second DNAI1 alteration (Failly M et al. Respiration, 2008 Apr;76:198-204). This amino acid position is highly conserved in available vertebrate species. Based on data from ExAC, the C allele has an overall frequency of approximately <0.01% (1/106200). In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the majority of available evidence to date, this variant is likely to be pathogenic. |
