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: Pathogenic
Review Status: criteria provided, single submitter
Collection Method: clinical testing

For this patient, the lab reported the c.6727C>T (p.R2243X) variant as pathogenic and the c.2966G>A (p.R989Q) as a VUS. Sent a nasal biopsy for ciliary beat frequency analysis and results came back inconclusive, but beating pattern was analgous to other DNAH11 mutation beating patterns. -

Significance: Pathogenic
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.009%). Predicted Consequence/Location: Stop-gained (nonsense): predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant. The variant has been reported at least twice as pathogenic with clinical assertions and evidence for the classification (ClinVar ID: VCV000289324 /PMID: 26729821). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -

Primary ciliary dyskinesia Pathogenic:1
Jan 23, 2025
Labcorp Genetics (formerly Invitae), Labcorp
Significance: Pathogenic
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change creates a premature translational stop signal (p.Arg2243*) 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 (rs201943194, gnomAD 0.02%). This premature translational stop signal has been observed in individual(s) with primary ciliary dyskinesia (PMID: 26729821, 31607746). ClinVar contains an entry for this variant (Variation ID: 289324). For these reasons, this variant has been classified as Pathogenic. -
