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:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely 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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This DNAH1 missense variant (rs374191991) is rare (<0.1%) in a large population dataset (gnomADv4.1.0: 53/1613314 total alleles; 0.003%; no homozygotes) and has been reported in ClinVar (Variation ID: 566754). It has not been reported in the literature in individuals with primary ciliary dyskinesia 7, to our knowledge. Two bioinformatics tools predict that the substitution would be damaging and the arginine residue at this position is evolutionarily conserved across many of the vertebrate species assessed. We consider the clinical significance of DNAH11 c.1643A>T to be uncertain at this time.
