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 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 28, 2021 | This sequence change replaces asparagine with serine at codon 2665 of the DNAH5 protein (p.Asn2665Ser). The asparagine residue is highly conserved and there is a small physicochemical difference between asparagine and serine. This variant is present in population databases (rs774224537, ExAC 0.002%). This variant has not been reported in the literature in individuals affected with DNAH5-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. - |
