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.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.I3744M variant (also known as c.11232C>G), located in coding exon 69 of the DNAH11 gene, results from a C to G substitution at nucleotide position 11232. The isoleucine at codon 3744 is replaced by methionine, an amino acid with highly similar properties. This variant was detected in conjunction with a second DNAH11 missense variant in an individual with hearing loss; however, phase and additional clinical information was not provided (Wonkam A et al. Commun Biol, 2022 Apr;5:369). This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is conflicting at this time, the clinical significance of this alteration remains unclear. -
