1268: A Genetic Map of the Canine Genome
Grant Status: Closed
This project contributed to the completion of the map of the canine genome. Researchers developed more than 400 microsatellite markers for placement on the map. By the end of this project, a third-generation linkage map was created, spanning 95 percent of the canine genome and containing 335 densely placed markers. The project exceeded the Foundation's goal of developing a dog genome map of 250 markers within three years. The researchers also developed screening sets of markers that have the highest likelihood of being informative, called minimal mapping set 1. At the end of the project, the linkage map had already been used to find several disease genes, including that for canine progressive rod-cone disease (prcd), a form of progressive retinal atrophy, in Labrador Retrievers, Portuguese Water Dogs, Poodles, English and American Cocker Spaniels, and potentially more breeds. Research continues to map more markers. This growing database of knowledge provides the basis for other researchers to find genes that cause diseases in dogs.

Help Future Generations of Dogs
Participate in canine health research by providing samples or by enrolling in a clinical trial. Samples are needed from healthy dogs and dogs affected by specific diseases.
