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.

The DNAH11 c.8798-5G>A variant (rs189821372) is reported in the literature in an individual affected with primary ciliary dyskinesia who harbored another DNAH11 variant (c.3544C>T; p.Arg1182Ter) in trans (Shoemark 2018). The c.8798-5G>A variant is reported in ClinVar (Variation ID: 163114) and is found in the general population with an overall allele frequency of 0.3759% (952/253,256 alleles, including 9 homozygotes) in the Genome Aggregation Database. This is an intronic variant in a weakly conserved nucleotide, but computational analyses (Alamut Visual Plus v.1.5.1) predict that this variant may impact splicing by creating a novel cryptic acceptor splice site. However, the splicing impact of this variant would need to be determined by functional studies. Due to limited information, the clinical significance of this variant is uncertain at this time.
