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 Pathogenic:1Uncertain:1
Jul 30, 2019
Undiagnosed Diseases Network, NIH
Significance:Likely pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

For this patient, the lab reported the c.6727C>T (p.R2243X) variant as pathogenic and the c.2966G>A (p.R989Q) as a VUS. We sent a nasal biopsy for ciliary beat frequency analysis and the results came back inconclusive, but the beating pattern was analogous to other DNAH11 mutation beating patterns.

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:curation

The p.Arg989Gln variant in DNAH11 has been reported in 2 individuals with primary ciliary dyskinesia (PMID: 31607746, 38562900) and has been identified in 0.004% (3/82028) of South Asian chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP ID: rs1178187217). 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: 453287) and has been interpreted as pathogenic by Undiagnosed Diseases Network (NIH) and as a variant of uncertain of significance by Invitae and Institute Of Molecular Biology And Genetics (Federal Almazov National Medical Research Centre). Of the 2 affected individuals, 1 was a compound heterozygotes that carried a reported pathogenic variant in trans which increases the likelihood that the p.Arg989Gln variant is pathogenic (Variation ID: 289324, PMID: 31607746). Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Arg989Gln variant is uncertain. ACMG/AMP Criteria applied: PM3, PM2_supporting (Richards 2015).

Primary ciliary dyskinesia Uncertain:2
Dec 12, 2024
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 989 of the DNAH11 protein (p.Arg989Gln). This variant is present in population databases (no rsID available, gnomAD 0.0008%). This missense change has been observed in individual(s) with clinical features of primary ciliary dyskinesia (PMID: 31607746). 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: 453287). 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) indicates that this missense variant is not expected to disrupt DNAH11 protein function with a negative predictive value of 95%. 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.

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

This sequence change replaces arginine (basic and polar) with glutamine (charge-neutral and polar) at codon 989 of the DNAH11 protein (p.Arg989Gln). The variant c.2966G>A has a low allele frequency in gnomAD Genomes (Version 3.1.2: ƒ = 0.000013). Particular in silico pathogenicity prediction tools (MetaRNN, MutPred, DANN, EIGEN PC, Mutation assessor, etc) predicted the c.2966G>A to be likely deleterious. ClinVar contains an entry for this variant (records with likely pathogenic and VUS interpretations (variation ID 453287)). The patient possessed the c.2966G>A variant in trans with another rare missense variant in DNAH11 (c.2824C>A, p.Pro942Thr). 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.

Variant summary: DNAH11 c.2966G>A (p.Arg989Gln) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4.5e-06 in 1566648 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.2966G>A has been reported in the literature in at least one compound heterozygous individual affected with clinical features of Primary Ciliary Dyskinesia 7 (e.g., Lee_2020). However, these data do not allow any conclusion about variant significance. 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: 31607746). ClinVar contains an entry for this variant (Variation ID: 453287). Based on the evidence outlined above, the variant was classified as uncertain significance.
