Could your twitching dog be the clue to curing a deadly childhood disease?
Most of you reading the title of this article will probably frown
their eyebrows, but please read on, because your dog could be able
to provide the clue needed to treat a terrible neurologic disease
that strikes children down hard, in the prime of their lives.
Two experienced veterinary neurologists, Dr. Susan Fitzmaurice and
Dr. Clare Rusbridge have been confronted in the last few years with
Miniature Wirehaired Dachshunds having epileptic seizures after the
age of 7. The fits were provoked by flashing lights, watching
television or if approached in sunlight. Sue and Clare went to great
lengths to establish a diagnosis for these dogs and with the help of
two veterinary pathologists (Dr. Diane Shelton, San Diego,
California, and Dr. Robin Franklin, Cambridge, England) they came to
the conclusion that this disease was the same as the deadly human
disease, Lafora's Progressive Myoclonus Epilepsy. Fortunately, the
disease in the dogs is much less severe than its human counterpart.
My name is Berge Minassian, I am a paediatric neurologist and
scientist dedicated to understanding, and hopefully one day curing
this devastating condition. This disease, in humans, strikes
otherwise completely normal children, just as they are entering
adolescence. Once the fits start, they do not stop, despite our best
efforts. The seizures get worse and worse until they kill the child.
Because of the onset of the disease after 10 years of age, many of
the families, not knowing what is brewing in their first child, have
had further children, who witness the ordeal of their sibling, only
to themselves then starting to succumb to the condition. Our
research laboratory is part of the large Center for Applied Genomics
at the Hospital for Sick Children in Toronto, Canada and is headed
by Dr. Stephen Scherer. This is the same lab which was involved in
such seminal discoveries as the gene for Cystic Fibrosis. We have
already discovered one gene for Lafora's disease. Surprisingly, we
also discovered that in humans, there is a second gene, which also
causes this horrible disease. This second Lafora's disease gene has
been very hard to find in humans. We now know that this second
Lafora's disease gene is the same gene causing the problem in the
Miniature Wirehaired Dachshunds. If we can find the Dachshund Lafora
gene, then that would be a major leap forward in unravelling the
biology of this disease in humans. We would be much closer to a
fuller understanding of what is going on, and hence much closer to a
potential cure for our children.
We are planning NO EXPERIMENTS OF ANY KIND on the dogs. What we need
is a little bit of blood, that is all. If you have a Miniature
Wirehaired Dachshund who has fits, THEN PLEASE CONTACT US, and allow
your puppy to give us a little bit of blood. Epilepsy is common in
dogs, and there are many forms of epilepsy. Please contact us only
if your dog is a miniature wirehaired dachshund. Many children in
the future will look back at this and will be eternally grateful.
Dr. Susan Fitzmaurice (in Woking) and Dr. Clare Rusbridge (in
Wimbledon) will be in charge of the blood collection in the U.K. All
reasonable costs will be covered by our research funds. Their
addresses are below. Any of you can contact me any time, and 1 will
do what 1 can to answer your questions, and help coordinate this
effort. My full address is also below.
Finally, do remember that the disease is much milder in the dogs.
The dogs have an altogether normal life apart from the fits late as
they age.
