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.

Pathogenic, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Jan 07, 2016	The p.Arg1445X variant in DNAH11 has been reported in 1 individual with PCD, and segregated with disease in 1 affected sibling (Knowles 2012). Both of these ind ividuals carried the variant in the homozygous state. This variant was also iden tified in 2/65366 European chromosomes by the Exome Aggregation Consortium (ExAC , http://exac.broadinstitute.org; dbSNP rs72657316). Although this variant has b een seen in the general population, its frequency is low enough to be consistent with a recessive carrier frequency. This nonsense variant leads to a premature termination codon at position 1445, which is predicted to lead to a truncated or absent protein. In summary, the p.Arg1445X variant meets our criteria to be cla ssified as pathogenic for PCD in an autosomal recessive manner. -
Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Dec 30, 2023	This sequence change creates a premature translational stop signal (p.Arg1445*) in the DNAH11 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DNAH11 are known to be pathogenic (PMID: 18022865, 20513915, 22184204). This variant is present in population databases (rs72657316, gnomAD 0.005%). This premature translational stop signal has been observed in individual(s) with primary ciliary dyskinesia (PMID: 22184204). ClinVar contains an entry for this variant (Variation ID: 228332). For these reasons, this variant has been classified as Pathogenic. -
