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.

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

This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 2169 of the DNAH11 protein (p.Ser2169Leu). This variant is present in population databases (rs373946181, gnomAD 0.06%). This missense change has been observed in individual(s) with clinical features of primary ciliary dyskinesia (PMID: 29467202; internal data). ClinVar contains an entry for this variant (Variation ID: 658037). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on DNAH11 protein function. For these reasons, this variant has been classified as Pathogenic. -

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

The p.S2169L variant (also known as c.6506C>T), located in coding exon 39 of the DNAH11 gene, results from a C to T substitution at nucleotide position 6506. The serine at codon 2169 is replaced by leucine, an amino acid with dissimilar properties. This alteration has been detected in the homozygous state, and in conjunction with a pathogenic DNAH11 mutation, in multiple unrelated individuals with primary ciliary dyskinesia (Shoemark A et al. Eur Respir J, 2018 02;51:; Ambry internal data). This amino acid position is highly 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. -

Primary ciliary dyskinesia 7 Pathogenic:2
Apr 09, 2025
Women's Health and Genetics/Laboratory Corporation of America, LabCorp
Significance:Likely pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

Variant summary: DNAH11 c.6506C>T (p.Ser2169Leu) results in a non-conservative amino acid change in the encoded protein sequence. Three of four in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 6.8e-05 in 249062 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in DNAH11 causing Primary Ciliary Dyskinesia 7, allowing no conclusion about variant significance. c.6506C>T has been reported in the homozygous and presumed compound heterozygous state in the literature and at Labcorp in multiple individuals affected with Primary Ciliary Dyskinesia 7 (e.g., Shoemark_2018, internal data). A further affected individual with primary ciliary dyskinesia with a biallelic genotype has been reported by another laboratory, however the details of that case were not available (Ambry Genetics, ClinVar). These data indicate that the variant may be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication has been ascertained in the context of this evaluation (PMID: 29467202). ClinVar contains an entry for this variant (Variation ID: 658037). Based on the evidence outlined above, the variant was classified as likely pathogenic. -
