CANINE EPILEPSY RESEARCH

"It only takes a minute!"

Canine epilepsy is one of the most emotionally devastating problems facing dog owners and breeders today. Dr. Gary S. Johnson, a molecular geneticist from the College of Veterinary Medicine at the University of Missouri-Columbia is currently doing DNA research to try to locate the mutation(s) responsible for causing epilepsy in dogs. The genes controlling seizure problems in dogs are not well understood, but this project is attempting to find the marker(s) or mutation(s) responsible. When these can be identified, a blood test will tell if an individual dog is a carrier, clear, or likely to become an affected (even before symptoms begin). Using this information, breeders can choose breeding partners who will not produce additional affected puppies.

Researchers working on this project need information from affected dogs and their families. Specifically, what is needed is a 3- to 5-generation pedigree of the litter where an affected dog (or dogs) appeared, and blood samples from the affected dog(s), all full siblings, parents, and when possible, the grandparents. More distant relatives are potentially useful, but the most important samples are from the affected dogs, their siblings, and parents. Family groups are important so that the genotype of the affected dogs can be compared to that of close relatives who are not affected, and allow researchers to decipher how these genes are inherited from one generation to the next. An affected dog with little or no family available may also be of some use.

Participation in the project is confidential - the names of dogs and owners who participate in the research will not be revealed. When the research produces results, individual owners will be able to request the results of testing on their own dogs. Results of research are published in such a way that the identity of individual dogs is anonymous.

There is a packet of information sheets and forms for submitting samples. You may make copies and distribute them to other interested breeders and owners. The packet can be downloaded at the Canine Epilepsy Network website, or upon request, may be faxed or mailed to you.

A recently funded grant from the AKC Canine Health Foundation allows participation in this research to be opened to affected dogs and their families in ALL breeds of dogs, at no cost to the owners or the breed parent clubs. As of November 23, 1999, samples have been received from over 940 dogs representing 25 different breeds. Within a year, researchers are looking for samples from families representing at least 50 breeds. It is hoped that information discovered in one breed may help locate mutations in another. Please spread the word of this research to anyone who has an affected dog or a relative of an affected dog, and to veterinarians and others who may come in contact with other dogs and owners who should be included. There is no cost to participate, other than a vet fee for drawing a blood sample (many vets are doing this at a reduced cost to support the research) and overnight shipping charges to the lab ($15-$35 from most places in the country via FedEx, UPS, or US Mail).
