Dear Ms. Bedsted, I am writing to you because I see on the YTCA website that you are the chairperson of the YTCA health committee. I want to let you know of a finding that we have made recently at OptiGen through our research/free testing program. A Yorkshire Terrier that was diagnosed with Progressive Retinal Atrophy (PRA) was sent to us for free testing and we have found that the cause of that PRA is prcd-PRA. This particular Yorkshire comes from a line of champions and so I am concerned that prcd-PRA may be present to a significant extent in the breed. I have spoken with the owners of the affected dog to let them know that we will add Yorkshire Terriers to the list of breeds that can make use of OptiGen DNA testing. This will allow them to test their line for any Carriers and to prevent the production of any prcd-Affected offspring in their future breedings. In looking at the CERF statistics, I see the PRA is not that uncommon in Yorkshires --2-4% of the Yorkshires that were examined between 2000-2005 were diagnosed with PRA. Although it is never a happy
day when a hereditary disease is identified in one's beloved breed, I am
hopeful that breeders will recognize what a great advantage it is to have
a DNA test immediately available to detect any carriers of the disease
in the population. There is information on our website about prcd
Also, I would be very happy to
answer any questions or discuss this finding anytime.
