Health Committee
Report - April 2005
Vicki Daitch,
chairperson Vicki@pngusa.net
The health committee
is working closely with researchers, other breed clubs, and the AKC’s
Canine Health Foundation (CHF) to plan and participate in research that
might be beneficial to malamutes and to provide up-to-date health
information to malamute fanciers.
Members will soon be
receiving a health survey in the mail if you have not already done so.
This survey deals specifically with hair and coat problems in malamutes,
with emphasis on alopecia (coat funk). Let me warn you that the survey
is a little complicated, but please don’t be deterred! Coat and skin
problems are complicated disorders, and we need your input.
Even if you do not
have a dog with coat problems, it is very important that you fill out
your survey where indicated.
In this way we can learn how prevalent coat problems are and how coat
disorder dogs compare with normal dogs. You should fill out the survey
only for dogs that you currently own or co-own. Do not fill out
a survey for anyone else’s dogs!
Because the survey
is done through the Virginia-Maryland Regional College of Veterinary
Medicine, it is critical that you complete and return your survey right
away. The veterinarians and students working on the project have a
limited amount of time because of the way semesters are set up, and it
is imperative to finish the project – including tallying and analyzing
the responses -- before graduation and summer vacation. The more
responses we have to work with, the better our information will be.
Through the health
committee’s connections with veterinary dermatologists, Dr. Linda Frank
of the University of Tennessee has agreed to give a Breeder’s Education
talk about canine alopecia at the National Specialty this year. She is
currently working on a study dealing with Pomeranian alopecia, and we
look forward to learning what she has found so far. We are looking
into doing a study using malamutes when her current work is complete.
Connections with
other breed clubs and foundations have been a tremendous help in working
out how best to attack health problems in malamutes. We are especially
happy to be working with Sheila Blanker (Morrissey), DVM of the Siberian
Husky Club of America. Dr. Blanker and I had talked last year about
initiating a thyroid study to determine whether malamutes and other
northern breeds might have slightly lower normal thyroid values than are
reflected by the all-breed reference range currently in use at
laboratories. When Sheila heard about exactly this kind of study to
being proposed by a university laboratory, she contacted the researcher
and then contacted me. We have now been formally asked to participate
in this study, pending approval of funding, thanks to the flow of
information through networking with other breed clubs and researchers.
You’ll recall that
AMCA is helping to fund CHF grant no. 305, a study to determine whether
histocompatibility alleles can be used to identify dogs at risk of
developing or passing on autoimmune diseases. The committee has been
working with the principal investigator, Dr. Wayne Potts at the
University of Utah, to help get sample DNA. Because malamutes
reportedly have a high incidence of autoimmune thyroiditis, and we hear
occasional reports of diabetes and hemolytic anemia, we hoped that we
could provide him with at least a few samples. The information about
how to participate in the study is on the Malamute Health web site (www.malamutehealth.org/grant305.htm).
Dr. Potts has gotten
several participants from other breeds via our web site, but only
one malamute so far! If your dog has been diagnosed with hemolytic
anemia, diabetes, or thyroid disease, please print the consent form from
the web site and take it to your veterinarian to determine whether your
dog is a good candidate for the study. If the malamute breed fancy is
to be taken seriously by the research community, we need to put our
money – and our dogs – where our mouths are. Even if the dog is
deceased, if you have stored semen, hair with roots, tissue samples, or
even baby teeth, it is possible that the dog might contribute
posthumously to this important study if his or her diagnosis fits the
profile.
The AMCA board of
directors has designated me to be the official club liaison for AKC CHF.
I am enjoying working with Erica Werne, the director of grants. She has
been unfailingly helpful and informative. I asked her about Dr.
Johnson’s grant no. 2290, a University of Missouri study purporting to
scan Pomeranian, Keeshund, and malamute DNA for alopecia-related genes.
That study is now finished, and according to Erica, Dr. Johnson has not
asked to renew the grant at this time.
As you all know, the
CHF was founded by and is generously funded by the American Kennel
Club. Now the AKC wants to establish an endowment to permanently
support the mission of the CHF. This endowment would, according to the
AKC’s press release, allow for “annual operating costs to be financed by
interest as opposed to donor contributions.” In other words, after this
endowment is established, every penny donated will go to actual health
research, rather than some of it having to pay for administrative
costs. AKC has already donated $500,000, and will offer matching
donations up to another $500,000. You can contribute to this goal by

www.akcchf.org.
We hear a lot of
discussion about getting DNA tests for various disorders, and it’s worth
saying a few words about why that’s not as easy as it sounds. For one
thing, many of the most devastating diseases are polygenic, caused by
the unfortunate confluence of multiple genes in a single animal. For
another, finding one gene that influences a particular trait is much
more difficult that finding a needle in a haystack!
It literally takes
millions of dollars sometimes to find a single gene or marker that can
be associated unequivocally with a particular disease. If it were
inexpensive and easy to do, we would have more DNA tests for human
diseases! Because we don’t have the money to fund an all-out assault on
the canine genome to identify a gene or two, we must wait and watch for
promising discoveries in other species or other breeds that narrow down
the search to a manageable project. We can also participate in studies
that are already funded by contributing sample DNA wherever possible.
For example, I’ve
been hearing rumors that epilepsy is a growing problem in our breed.
Canine epilepsy researchers of at least two institutions are soliciting
DNA from complete families of dogs with at least two affected
dogs to help look for genetic commonalities. That may mean, for
example, a mother, father, and all their offspring, where two offspring
or one parent and one offspring are affected. Even better would be
three generations. For some examples of the kinds of sample families
that would be most helpful, see
www.vetgen.optimal.com/html and
www.canine-epilepsy.net/pedigrees.html. You can also find more
information about ongoing research into canine epilepsy on these web
sites. This is a way in which breeders with access to complete families
of dogs can quietly participate in important research. If you choose to
participate, you are a hero – thank you!
