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]

This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 3428 of the DNAH5 protein (p.Ala3428Thr). This variant is present in population databases (rs760220268, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with DNAH5-related conditions. ClinVar contains an entry for this variant (Variation ID: 407250). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Primary ciliary dyskinesia 3 Uncertain:1
May 20, 2023
Neuberg Centre For Genomic Medicine, NCGM
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The missense c.10282G>A (p.Ala3428Thr) variant in the DNAH5 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is reported with the allele frequency (0.002%) in the gnomAD Exome. This variant has been reported to the ClinVar database as Uncertain Significance. However, no details are available for independent assessment. The amino acid Alanine at position 3428 is changed to a Threonine changing protein sequence and it might alter its composition and physico-chemical properties. Multiple lines of computational evidence (Polyphen - Probably damaging, SIFT – Damaging and MutationTaster - Disease causing) predict a damaging effect on protein structure and function for this variant. The amino acid change alanine in DNAH5 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance. -
