Genes affected

DNAH11 (HGNC:2942): (dynein axonemal heavy chain 11) This gene encodes a ciliary outer dynein arm protein and is a member of the dynein heavy chain family. It is a microtubule-dependent motor ATPase and has been reported to be involved in the movement of respiratory cilia. Mutations in this gene have been implicated in causing Kartagener Syndrome (a combination of situs inversus totalis and Primary Ciliary Dyskinesia (PCD), also called Immotile Cilia Syndrome 1 (ICS1)) and male sterility.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This nonsense variant results in a premature stop codon in exon 53, likely leading to nonsense-mediated decay and lack of protein production. DNAH11 c.8698C>T has been reported in numerous patients presenting with primary ciliary dyskinesia. This variant (rs368260932) is rare (<0.1%) in a large population dataset (gnomAD: 13/280318 total alleles; 0.005%; no homozygotes) and has been reported in ClinVar. We consider this variant to be pathogenic. -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change creates a premature translational stop signal (p.Arg2900*) in the DNAH11 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DNAH11 are known to be pathogenic (PMID: 18022865, 20513915, 22184204). This variant is present in population databases (rs368260932, gnomAD 0.01%). This premature translational stop signal has been observed in individual(s) with primary ciliary dyskinesia (PMID: 22102620, 24450482, 26139845). This variant is also known as R2907X. ClinVar contains an entry for this variant (Variation ID: 36981). For these reasons, this variant has been classified as Pathogenic. -

Collection Method: clinical testing

The p.R2900* pathogenic mutation (also known as c.8698C>T), located in coding exon 53 of the DNAH11 gene, results from a C to T substitution at nucleotide position 8698. This changes the amino acid from an arginine to a stop codon within coding exon 53. This mutation has been reported in individuals with primary ciliary dyskinesia (PCD), including one homozygous individual with otitis media, sinusitis, cough, bronchiectasis, normal ciliary ultrastructure, and abnormal ciliary beating on video microscopy (Lucas JS et al. Hum. Mutat., 2012 Mar;33:495-503; Boon M et al. Orphanet J Rare Dis, 2014 Jan;9:11; Dougherty GW et al. Am. J. Respir. Cell Mol. Biol., 2016 Aug;55:213-24). 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. -
