Cross-species summary: Motile cilia are required for clearing mucous, infectious agents and inhaled dust from the airways. Primary ciliary dyskinesia (PCD) is a hereditary defect of motile cilia. Clinical findings may include recurrent airway infections, fertility problems, and sometimes hydrocephalus. (Tosso Leeb 10 Sep 2019)

Species-specific description: Several types of primary ciliary dyskinesia exist. See also 'OMIA001540-9615 : Ciliary dyskinesia, primary, CCDC39-related in Canis lupus familiaris' and 'OMIA000573-9615 : Ciliary dyskinesia, primary, generic in Canis lupus familiaris'.

Molecular basis: Anderegg et al. (2019): "Whole genome sequencing of one [Alaskan Malamute] case and comparison to 601 control genomes identified a disease associated frameshift variant, c.43delA, in the NME5 gene encoding a sparsely characterized protein associated with ciliary function. . . . The genotypes at NME5:c.43delA showed the expected co-segregation with the phenotype in the Alaskan Malamute family. An additional unrelated Alaskan Malamute with PCD and hydrocephalus that became available later in the study was also homozygous mutant at the NME5:c.43delA variant". Immunohistochemistry demonstrated absence of the NME5 protein from nasal epithelia of an affected dog.

Clinical features: Anderegg et al. (2019): "severe bronchial lung pattern and bronchiectasis on thoracic radiographs in both dogs . . . Direct rhinoscopy and bronchoscopy revealed hyperemic mucosa, medium to large amount of mucopurulent secretions along the upper and lower airway tracts and moderate to severe turbinate lysis in the nasal cavity in both dogs . . . Bronchoalveolar lavage fluid was compatible with chronic active purulent bronchopneumonia."

Pathology: Electron microscopy of cilia from nasal epithelium revelaed alterations at the inner and outer dynein arms of motile cilia. Inner dynein arms were shortened or absent in 95% - 100% of the investigated cilia, outer dynein arms were shortend or absent in 60% - 80% of cilia. In normal cilia, there is a 9 + 2 arrangement of microtubules with two single microtubules in the center and nine pairs of peripheral microtubules. In an affected dog, extra peripheral microtubule singlets appeared occasionally (Anderegg et al. 2019).

Prevalence: Anderegg et al. (2019): "The mutant allele was not present in more than 1000 control dogs from different breeds."

Breed: Alaskan Malamute (Dog) (VBO_0200017).

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.

Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
