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.

Uncertain significance, criteria provided, single submitter	clinical testing	UNC Molecular Genetics Laboratory, University of North Carolina at Chapel Hill	Feb 16, 2021	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Jun 13, 2022	This sequence change replaces glutamine, which is neutral and polar, with histidine, which is basic and polar, at codon 2660 of the DNAH11 protein (p.Gln2660His). This variant is present in population databases (rs752284064, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with DNAH11-related conditions. ClinVar contains an entry for this variant (Variation ID: 572615). 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. 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. -
Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Oct 12, 2022	The c.7980A>C (p.Q2660H) alteration is located in exon 49 (coding exon 49) of the DNAH11 gene. This alteration results from a A to C substitution at nucleotide position 7980, causing the glutamine (Q) at amino acid position 2660 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
