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]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 5-13708130-C-T is Pathogenic according to our data. Variant chr5-13708130-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 407247.Status of the report is criteria_provided_single_submitter, 1 stars.

Collection Method: clinical testing

This sequence change creates a premature translational stop signal at codon 4444 (p.Trp4444*) of the DNAH5 gene. It is expected to result in an absent or disrupted protein product. For these reasons, this variant has been classified as Pathogenic. While this particular variant has not been reported in the literature, loss-of-function variants in DNAH5 are known to be pathogenic (PMID: 16627867, 11788826). -
