Genes affected

DNAH5 (HGNC:2950): (dynein axonemal heavy chain 5) This gene encodes a dynein protein, which is part of a microtubule-associated motor protein complex consisting of heavy, light, and intermediate chains. This protein is an axonemal heavy chain dynein. It functions as a force-generating protein with ATPase activity, whereby the release of ADP is thought to produce the force-producing power stroke. Mutations in this gene cause primary ciliary dyskinesia type 3, as well as Kartagener syndrome, which are both diseases due to ciliary defects. [provided by RefSeq, Oct 2009]

Primary ciliary dyskinesia

Pathogenic:2

Likely pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	Feb 23, 2019	The p.W3409S variant (also known as c.10226G>C), located in coding exon 60 of the DNAH5 gene, results from a G to C substitution at nucleotide position 10226. The tryptophan at codon 3409 is replaced by serine, an amino acid with highly dissimilar properties. This variant was reported in an individual with primary ciliary dyskinesia (characterized by outer dynein arm defects on electron microscopy) in trans with a nonsense variant in DNAH5 (Hornef N et al. Am. J. Respir. Crit. Care Med., 2006 Jul;174:120-6). This amino acid position is highly conserved in available vertebrate species. 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. -
Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Jan 11, 2024	This sequence change replaces tryptophan, which is neutral and slightly polar, with serine, which is neutral and polar, at codon 3409 of the DNAH5 protein (p.Trp3409Ser). This variant is present in population databases (rs755407407, gnomAD 0.002%). This missense change has been observed in individual(s) with primary ciliary dyskinesia (PMID: 16627867; 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: 238952). 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 DNAH5 protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. -
