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	Institute of Human Genetics, University Hospital Muenster	Jan 25, 2022	ACMG categories: PVS1,PM3,PP5 -

Pathogenic, criteria provided, single submitter	clinical testing	Johns Hopkins Genomics, Johns Hopkins University	Oct 22, 2021	DNAH5 c.5563dupA has been reported in multiple individuals with primary ciliary dyskinesia. This variant (rs752925056) is rare (<0.1%) in a large population dataset (gnomAD: 17/282580 total alleles; 0.006%; no homozygotes) and has been reported in ClinVar. This frameshift variant results in a premature stop codon in exon 34 likely leading to nonsense-mediated decay and lack of protein production. We consider DNAH5 c.5563dupA to be pathogenic. -
Pathogenic, no assertion criteria provided	clinical testing	Prenatal Genetic Diagnosis Laboratory, The Chinese University of Hong Kong	Mar 25, 2021	This variant c.5563dupA(p.I1855fs) creates a premature termination codon in exon 34, where nonsense-mediated decay is predicted to occur. The mechanism of pathogenicity in DNAH5 mutations appears to be bi-allelic loss of function [PMID: 16627867] (PVS1). This variant is extremely rare in the gnomAD database (PM2). It was previously reported in patients with primary ciliary dyskinesia and atrial and ventricular septal defects and found to be in trans configuration with another damaging variant or as a homozygote [PMID: 11788826, 28991257, 31118369, 31772028, 32622824] (PM3). It is interpreted as pathogenic according to ACMG/AMP guidelines. -
Pathogenic, criteria provided, single submitter	clinical testing	Centre for Mendelian Genomics, University Medical Centre Ljubljana	Mar 12, 2020	This variant was classified as: Pathogenic. The following ACMG criteria were applied in classifying this variant: PVS1,PP1,PP3. -

Pathogenic, no assertion criteria provided	clinical testing	Natera, Inc.	Sep 16, 2020	- -
Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Jan 27, 2024	This sequence change creates a premature translational stop signal (p.Ile1855Asnfs*6) in the DNAH5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DNAH5 are known to be pathogenic (PMID: 11788826, 16627867). This variant is present in population databases (rs752925056, gnomAD 0.03%). This premature translational stop signal has been observed in individuals with primary ciliary dyskinesia (PMID: 11788826, 25186273, 26228299). ClinVar contains an entry for this variant (Variation ID: 407241). For these reasons, this variant has been classified as Pathogenic. -
Pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	Sep 19, 2022	The c.5563dupA pathogenic mutation, located in coding exon 34 of the DNAH5 gene, results from a duplication of A at nucleotide position 5563, causing a translational frameshift with a predicted alternate stop codon (p.I1855Nfs*6). This alteration has been detected in the homozygous state, or in conjunction with another DNAH5 mutation, in multiple individuals with primary ciliary dyskinesia (Hornef N et al. Am J Respir Crit Care Med, 2006 Jul;174:120-6; Guo Z et al. J Pediatr, 2020 10;225:157-165.e5; Kurokawa A et al. Respir Investig, 2021 Jul;59:550-554; Blanchon S et al. J Med Genet, 2020 04;57:237-244; Raidt J et al. Eur Respir J, 2014 Dec;44:1579-88; Djakow J et al. Pediatr Pulmonol, 2016 May;51:498-509). In addition, this alteration has been found to cosegregate with disease in four affected homozygous siblings with consanguineous parentage (Olbrich H et al. Nat. Genet., 2002 Feb;30:143-4; Omran H et al. Am. J. Respir. Cell Mol. Biol., 2000 Nov;23:696-702). This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -
