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]

Significance: Likely pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.D2796G variant (also known as c.8387A>G), located in coding exon 50 of the DNAH5 gene, results from an A to G substitution at nucleotide position 8387. The aspartic acid at codon 2796 is replaced by glycine, an amino acid with similar properties. This variant has been detected in in the homozygous state in an individual with situs inversus and bronchiectasis by our laboratory. 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. -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant is present in population databases (rs727502974, gnomAD 0.01%). For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Asp2796 amino acid residue in DNAH5. Other variant(s) that disrupt this residue have been determined to be pathogenic (Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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. ClinVar contains an entry for this variant (Variation ID: 163140). This missense change has been observed in individual(s) with primary ciliary dyskinesia (Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 2796 of the DNAH5 protein (p.Asp2796Gly). -
