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.

DNAH11 links:

CDCA7L (HGNC:30777): (cell division cycle associated 7 like) Acts upstream of or within positive regulation of cell population proliferation. Located in cytosol; fibrillar center; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

This variant, c.13351_13353del, results in the deletion of 1 amino acid(s) of the DNAH11 protein (p.Lys4451del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs552487543, gnomAD 0.006%). 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: 454660). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -
