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.

Primary ciliary dyskinesia 7 Uncertain:1
Feb 19, 2025
Broad Center for Mendelian Genomics, Broad Institute of MIT and Harvard
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: curation

The p.Leu3776Pro variant in DNAH11 has been reported, in the compound heterozygous state, in 1 individual with primary ciliary dyskinesia (PMID: 31772028), but has been identified in 0.001% (1/74936) of African/African American chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs751761608). Although this variant has been seen in the general population in a heterozygous state, its frequency is low enough to be consistent with a recessive carrier frequency. This variant has also been reported in ClinVar (Variation ID: 454640) and has been interpreted as a variant of uncertain significance by Invitae. Computational prediction tools and conservation analyses suggest that this variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, the clinical significance of the p.Leu3776Pro variant is uncertain. ACMG/AMP Criteria applied: PP3_moderate, PM3, PM2_supporting (Richards 2015). -

Primary ciliary dyskinesia Uncertain:1
Apr 13, 2019
Labcorp Genetics (formerly Invitae), Labcorp
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces leucine with proline at codon 3776 of the DNAH11 protein (p.Leu3776Pro). The leucine residue is highly conserved and there is a moderate physicochemical difference between leucine and proline. This variant is present in population databases (rs751761608, ExAC 0.002%). This variant has not been reported in the literature in individuals with DNAH11-related conditions. ClinVar contains an entry for this variant (Variation ID: 454640). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
