Genes affected
ODAD2 (HGNC:25583): (outer dynein arm docking complex subunit 2) The protein encoded by this gene contains ten Armadillo repeat motifs (ARMs) and one HEAT repeat, and is thought to be involved in ciliary and flagellar movement. This protein has been shown to localize to the ciliary axonemes and at the ciliary base of respiratory cells. Studies indicate that mutations in this gene cause partial outer dynein arm (ODA) defects in respiratory cilia. The cilia of cells with mutations in this gene displayed either reduced ciliary beat frequency and amplitude, or, complete immotility. Some individuals with primary ciliary dyskensia (PCD) have been shown to have mutations in this gene. PCD is characterized by chronic airway disease and left/right body asymmetry defects. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Aug 2015]

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

This sequence change creates a premature translational stop signal (p.Trp740*) in the ARMC4 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ARMC4 are known to be pathogenic (PMID: 23849778). This variant is present in population databases (rs201213030, ExAC 0.01%). This premature translational stop signal has been observed in individual(s) with primary ciliary dyskinesia (PMID: 23849778). For these reasons, this variant has been classified as Pathogenic. -
