A new mutation has recently been discovered in the Nova Scotia Duck Tolling Retriever that causes Primary Ciliary Dyskinesia (PCD). PCD is a hereditary disorder in which the microscopic cilia in the respiratory and reproductive tracts do not function properly. As a result, mucus and debris accumulate, leading to chronic inflammation and respiratory infections.
Although the scientific paper still needs to be published, this test is already available at CombiBreed under test code H133. The test for PCD has also been added to the CombiBreed panel for the Nova Scotia Duck Tolling Retriever.
