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]

Variant summary: DNAH5 c.1730G>C (p.Arg577Thr) results in a non-conservative amino acid change located in the Dynein heavy chain, tail domain (IPR013594) of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. Several computational tools predict a significant impact on normal splicing: Four predict the variant abolishes the canonical 5' splicing donor site. At least one publication reports experimental evidence that this variant leads to exon 13 skipping, resulting in premature protein truncation (example: Hofner_2006). The variant allele was found at a frequency of 2.2e-05 in 231028 control chromosomes (gnomAD). c.1730G>C has been reported in the literature in an individual affected with Primary ciliary dyskinesia (in heterozygous state), characterized by defective outer dynein arms on electron microscopy (example: Hofner_2006). The following publication has been ascertained in the context of this evaluation (PMID: 16627867). Four submitters have cited clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as VUS (n=1) and pathogenic/likely pathogenic (n=3). Based on the evidence outlined above, the variant was classified as likely pathogenic. -

Significance: Likely pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1730G>C variant (also known as p.R577T), located in coding exon 13 of the DNAH5 gene, results from a G to C substitution at nucleotide position 1730. The amino acid change results in arginine to threonine at codon 577, an amino acid with similar properties. However, this change occurs in the last base pair of coding exon 13, which makes it likely to have some effect on normal mRNA splicing. This variant was detected in a patient with primary ciliary dyskinesia (characterized by defective outer dynein arms on electron microscopy). A second alteration was not detected; however, studies of the patient's respiratory epithelial cells showed exon 13 skipping, resulting in premature protein truncation (Hornef N, Am. J. Respir. Crit. Care Med. 2006 Jul; 174(2):120-6). This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 6488 samples (12976 alleles) with coverage at this position. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the majority of available evidence to date, this variant is likely to be pathogenic. -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change affects codon 577 of the DNAH5 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the DNAH5 protein. RNA analysis indicates that this variant induces altered splicing and may result in an absent or altered protein product. This variant is present in population databases (rs397515541, gnomAD 0.004%). This variant has been observed in individual(s) with clinical features of primary ciliary dyskinesia (PMID: 16627867; internal data). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 65637). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Studies have shown that this variant results in skipping of exon 13, and produces a non-functional protein and/or introduces a premature termination codon (PMID: 16627867). For these reasons, this variant has been classified as Pathogenic. -
