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.

Benign:2

Benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Apr 29, 2024	This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

The Gln4323His variant in DNAH11 has not been previously identified in individua ls with pulmonary disease. This variant has been identified in 1/2178 chromosome s from a broad population by the 1000 Genomes Project (http://www.ncbi.nlm.nih.g ov/variation/tools/1000genomes/; dbSNP rs191802172). Glutamine at position 4223 is not well conserved in evolution, and the variant residue (Histidine) has been observed in one mammalian species (Egyptian Jerboa), suggesting that the change may be tolerated. Additional computational analyses (biochemical amino acid pro perties, AlignGVGD, PolyPhen2, and SIFT) do not provide strong support for or ag ainst an impact to the protein. In summary, additional information is needed to fully assess its clinical significance. -
