Abstract
Defects in collagen proteins cause a variety of disorders in humans. It can be expected that collagen gene mutations are involved in collagenopathies in dogs. The collagen genes COL3A1, COL5A1, COL5A2, COL6A1, COL6A3, COL9A1, COL9A2, COL9A3, COL10A1 and COL11A1 were identified on the canine genome based on the homology with the human genes. Simple sequence repeats (microsatellites) were found in the chromosomal regions of these genes and investigated for polymorphism in Labrador Retrievers, Bernese Mountain dogs, Boxer dogs and German Shepherd dogs by PCR and subsequent detection of the DNA products. Nine informative microsatellite markers were identified. The markers closely situated to COL9A1, COL9A2 and COL9A3 were used to investigate the involvement of the genes in cranial cruciate ligament rupture in Boxer dogs. It was found that these genes are probably not involved in this abnormality. The markers described here will be useful for a candidate gene approach of suspected collagenopathies specific to dog breeds.
