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]

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 25, 2024	This sequence change replaces alanine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 2881 of the DNAH5 protein (p.Ala2881Gly). This variant is present in population databases (rs727502973, gnomAD 0.004%). This missense change has been observed in individual(s) with primary ciliary dyskinesia (PMID: 25186273, 26373788; Invitae). ClinVar contains an entry for this variant (Variation ID: 163139). 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 not expected to disrupt DNAH5 protein function with a negative predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. -
Pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	May 18, 2023	The p.A2881G pathogenic mutation (also known as c.8642C>G), located in coding exon 51 of the DNAH5 gene, results from a C to G substitution at nucleotide position 8642. The alanine at codon 2881 is replaced by glycine, an amino acid with similar properties. This mutation has been detected with another DNAH5 variant in multiple individuals with primary ciliary dyskinesia (Raidt J et al. Eur Respir J, 2014 Dec;44:1579-88; Raidt J et al. Hum Reprod, 2015 Dec;30:2871-80; Fassad MR et al. J Med Genet, 2020 May;57:322-330; Ambry internal data). Functional analysis also revealed that some of these individuals have defective outer dynein arm and/or cilia (Raidt J et al. Hum Reprod, 2015 Dec;30:2871-80; Fassad MR et al. J Med Genet, 2020 May;57:322-330). This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. -
