What possible results might I receive?

For each test, you have the possibility of receiving the following results: normal, carrier, or at-risk (affected).  Normal means that your dog has two copies of the "wildtype" or normal DNA sequence for the gene being tested.  Carrier means that your dog carries one copy of the "wildtype" sequence (normal) and one copy of the mutation.  For most diseases, your dog will not be affected with the disease, but simply a carrier.  Carriers can pass this mutated copy of the gene to half of their offspring and depending on the genetics of their mate, may produce at-risk or affected puppies.  An at-risk result means that your dog has two copies of the mutation and is at-risk for developing the disease. In this case, these dogs carry two copies of the mutation so that all offspring will inherit at least one copy of the mutation and depending on its mate, is at high-risk of producing affected puppies.
