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:no assertion criteria provided
Collection Method:clinical testing

The DNAH11 c.11924C>T variant is predicted to result in the amino acid substitution p.Ala3975Val. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.21% of alleles in individuals of South Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/7-21908566-C-T). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
