Primary Ciliary Dyskinesia (PCD) - Alaskan Malamute

Primary ciliary dyskinesia (PCD) is a genetic condition affecting motile cilia. Motile cilia are present in the respiratory tract, reproductive tract, brain and spinal cord. They are required for clearing mucous, infectious agents and inhaled dust from the airways. Clinical signs include fertility problems, chronic bronchitis, situs inversus (in about 50% of dogs), bronchopneumonia, bronchiectasis, hydrocephalus, chronic recurrent infections of the respiratory tract and chronic productive cough. PCD has been described in numerous dog breeds including Alaskan Malamutes. Some Alaskan Malamutes are euthanized due to chronic respiratory infections.

Inheritance: autosomal recessive

Mutation: NME5 gene

Genetic test: The method used for genetic testing is extremely accurate and allows complete differentiation between affected animals, carriers and healthy dogs. DNA testing can be done at any age.
