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:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change affects an acceptor splice site in intron 34 of the DNAH5 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in DNAH5 are known to be pathogenic (PMID: 11788826, 16627867). This variant is present in population databases (rs548521732, gnomAD 0.02%). Disruption of this splice site has been observed in individual(s) with primary ciliary dyskinesia (PMID: 19357118, 27637300). ClinVar contains an entry for this variant (Variation ID: 454788). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
