Banking to Benefit the Bouvier $
The
CHIC DNA Repository collects and stores samples of canine DNA, together
with corresponding genealogical and phenotypic information, to facilitate
future research and testing for reducing the incidence of inherited
disease in dogs.
The
ready availability of DNA material for research is gaining importance
as technology for utilizing DNA is rapidly expanding. With sufficient
deposits in the "DNA Bank" by owners, the CHIC DNA Repository can
provide researchers with optimized family groups and control populations
needed for their research into canine health.
As
research advances, breeders can take advantage of future DNA-based
disease tests. This potential remains with a DNA deposit even after
a dog is deceased. If a deleterious gene is discovered in an offspring
of a deceased dog, a DNA screening test on the stored sample can
determine the presence or absence of the gene in the ancestor and
thus whether other progeny might be at risk.
The
CHIC DNA Repository can foster a team environment among breeders,
owners and the researchers to increase the likelihood of genetic
discovery.
Blood
Sample
Blood
is the gold standard for genetic material. The yield of DNA from
a blood sample is sufficient for all research methods, including
technologies on the horizon. Moreover, the stability and purity
of the DNA is of the highest caliber, which offers many benefits.
While
banking of blood samples for DNA has advantages, it also has the
drawbacks of cost and invasiveness of drawing the blood.
The
banking organization, in this case CHIC, incurs the cost of extracting
the DNA from the blood sample, of entering data from a phenotypic
questionnaire about the donor-dog submitted with the sample and
on-going surveys that follow the health status of the dog, and of
storage and inventory control for samples and data.
The
cost to the owner is $20.00 to purchase the test kit from CHIC plus
the veterinary expense of drawing the blood and shipping the frozen
sample.
Cheek
Swab
Cheek
swab samples are less expensive and less invasive than blood samples,
but the yield and purity of DNA derived from cheek samples is inferior
to that obtained from blood.
A
swab kit can be purchased from CHIC for $5.00, and the samples can
be taken by the owner without the expense of a veterinary office
call. Swabs are shipped in standard envelopes through the U.S. Postal
Service, and they can be stored for at least a decade at room temperature,
so long as they are stored under conditions of low humidity. The
success rate for obtaining DNA from a swab in the laboratory is
roughly 98%, so multiple swabs should be submitted for each dog
to ensure representation in the archive.
Breed
specific advantages of accumulating adequate samples in the
CHIC DNA Repository are twofold:
- it
increases the likelihood that a researcher will choose to use
our breed for their project because of the readily accessible
study population and,
- because
the phenotypic health of donor dogs is followed, it can act to
raise an early alarm as a disease begins to infiltrate our breed.
To
Participate in the CHIC DNA Repository the application form can
be downloaded from http://www.caninehealthinfo.org/dnabank.html
You
will receive the appropriate swab or blood collection kit in the
mail. The health survey, which will accompany the sample deposit,
will also be found on-line.
