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.

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 1216 of the DNAH11 protein (p.Glu1216Lys). This variant is present in population databases (rs201197846, gnomAD 0.05%), including at least one homozygous and/or hemizygous individual. 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: 573903). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The lysine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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. -
