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.

Pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	Aug 26, 2021	The p.R1627C pathogenic mutation (also known as c.4879C>T), located in coding exon 28 of the DNAH11 gene, results from a C to T substitution at nucleotide position 4879. The arginine at codon 1627 is replaced by cysteine, an amino acid with highly dissimilar properties. This mutation has been detected in multiple individuals with a clinical diagnosis or suspicion of primary ciliary dyskinesia, who have another pathogenic mutation in DNAH11 (internal Ambry data). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Aug 15, 2022	This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 1627 of the DNAH11 protein (p.Arg1627Cys). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with heterotaxy and primary ciliary dyskinesia (Invitae). ClinVar contains an entry for this variant (Variation ID: 163104). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt DNAH11 protein function. This variant disrupts the p.Arg1627 amino acid residue in DNAH11. Other variant(s) that disrupt this residue have been observed in individuals with DNAH11-related conditions (PMID: 31772028; Invitae), which suggests that this may be a clinically significant amino acid residue. 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. -

The Arg1627Cys variant in DNAH11 has not been previously reported in individuals with lung disease or in large population studies. This residue is conserved in evolution and computational analyses (biochemical amino acid properties, AlignGV GD, PolyPhen2, and SIFT) predict that this variant will impact the normal functi on of the protein. In summary, this information is insufficient to establish the the clinical significance of the Arg1627Cys variant. -

This DNAH11 variant (rs727502967) is rare (<0.1%) in a large population dataset (gnomAD: 3/280426 total alleles; 0.001%; no homozygotes) and has not been reported in ClinVar nor the literature, to our knowledge. Two bioinformatic tools queried predict that this substitution would be damaging, and the arginine residue at this position is highly evolutionarily conserved across most species assessed. Due to insufficient evidence that this variant is deleterious, we consider the clinical significance of c.4879C>T to be uncertain at this time. -
