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	Labcorp Genetics (formerly Invitae), Labcorp	Jan 16, 2024	This sequence change replaces leucine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 1157 of the DNAH11 protein (p.Leu1157Arg). This variant is present in population databases (rs117830543, gnomAD 0.2%). This missense change has been observed in individual(s) with DNAH11-related conditions and/or primary ciliary dyskinesia (PMID: 31040315, 32502479; Invitae). 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: 359621). 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 not expected to disrupt DNAH11 protein function with a negative predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. -

Variant summary: DNAH11 c.3470T>G (p.Leu1157Arg) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00012 in 248870 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.3470T>G has been reported in the literature in compound heteozygous individuals affected with Primary Ciliary Dyskinesia 7 (Guo_2020, Cao_2022). 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 publications have been ascertained in the context of this evaluation (PMID: 35441720, 32502479, 31040315, 34133440, 34405951, 35518361). ClinVar contains an entry for this variant (Variation ID: 359621). Based on the evidence outlined above, the variant was classified as VUS-possibly pathogenic. -
