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 18 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 5-13793713-C-CTA is Pathogenic according to our data. Variant chr5-13793713-C-CTA is described in ClinVar as [Pathogenic]. Clinvar id is 407233.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Primary ciliary dyskinesia Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Jul 08, 2022	This variant has not been reported in the literature in individuals affected with DNAH5-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change creates a premature translational stop signal (p.Val2676*) in the DNAH5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DNAH5 are known to be pathogenic (PMID: 11788826, 16627867). ClinVar contains an entry for this variant (Variation ID: 407233). For these reasons, this variant has been classified as Pathogenic. -
Pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	Jun 12, 2015	The c.8024_8025dupTA pathogenic mutation, located in coding exon 49 of the DNAH5 gene, results from a duplication of TA at nucleotide position 8024, causing a translational frameshift with a predicted alternate stop codon. Since frameshifts are typically deleterious in nature, this alteration is interpreted as a disease-causing mutation (ACMG Recommendations for Standards for Interpretation and Reporting of Sequence Variations. Revision 2007. Genet Med. 2008;10:294). -
