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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change falls in intron 57 of the DNAH5 gene. It does not directly change the encoded amino acid sequence of the DNAH5 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs763440781, gnomAD 0.002%). This variant has been observed in individual(s) with clinical features of primary ciliary dyskinesia (Invitae). ClinVar contains an entry for this variant (Variation ID: 454819). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). 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. -
