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 Pathogenic:2
Dec 17, 2024
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Tyr84*) 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). This variant is present in population databases (rs754982008, gnomAD 0.003%). This premature translational stop signal has been observed in individual(s) with primary ciliary dyskinesia (PMID: 16627867). ClinVar contains an entry for this variant (Variation ID: 525260). For these reasons, this variant has been classified as Pathogenic. -

Significance:Pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.Y84* pathogenic mutation (also known as c.252T>G), located in coding exon 3 of the DNAH5 gene, results from a T to G substitution at nucleotide position 252. This changes the amino acid from a tyrosine to a stop codon within coding exon 3. This mutation was identified in an individual with primary ciliary dyskinesia and an outer dynein arm defect on electron microscopy; however, a second alteration was not detected (Hornef N et al. Am. J. Respir. Crit. Care Med., 2006 Jul;174:120-6). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -
