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
Pathogenic, criteria provided, single submitterclinical testingAmbry GeneticsSep 12, 2017The p.R742* pathogenic mutation (also known as c.2224C>T), located in coding exon 15 of the DNAH5 gene, results from a C to T substitution at nucleotide position 2224. This changes the amino acid from an arginine to a stop codon within coding exon 15. 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. -
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 19, 2024This sequence change creates a premature translational stop signal (p.Arg742*) 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 (rs776686983, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with DNAH5-related conditions. ClinVar contains an entry for this variant (Variation ID: 454757). 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. -
