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.

Likely benign, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 28, 2024	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Mar 03, 2020	The p.I792L variant (also known as c.2374A>C), located in coding exon 14 of the DNAH11 gene, results from an A to C substitution at nucleotide position 2374. The isoleucine at codon 792 is replaced by leucine, an amino acid with highly similar properties. This amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

This DNAH11 missense variant (rs762314534) is rare (<0.1%) in a large population dataset (gnomAD v4.0.0: 31/1613376 total alleles; 0.002%; 2 homozygotes). It has been reported in ClinVar (Variation ID 1055080), but has not been reported in the literature, to our knowledge. Two bioinformatic tools queried predict that this substitution would be tolerated, and while the isoleucine residue at this position is evolutionarily conserved across a few of the species assessed, most species have a different amino acid including several with leucine. We consider the clinical significance of c.2374A>C in DNAH11 to be uncertain at this time. -
