A Finnish - North American collaboration of scientists at Michigan State University and the University of Helsinki has found a MERTK gene defect responsible for a recently identified form
of progressive retinal atrophy in Swedish vallhund dogs.
Some of the other health problems your dog may be at risk for
include progressive retinal atrophy, patellar luxation, epilepsy, diabetes, Addison's disease, and Legg - Calve - Perthes Disease.
Large or dilated pupils could be a symptom of glaucoma, or other vision problems such
as progressive retinal atrophy which can lead to permanent blindness.
Dr. Johnson's proposal, entitled «Identification of Mutations Responsible
for Progressive Retinal Atrophy in TTs by Whole Genome Sequencing» can be seen on the TTWHF website.
The identification of MERTK gene as a cause of Swedish Vallhund PRA is the result of a decade - long project that first described the newly emerged disease in September 2014 in A Novel Form of
Progressive Retinal Atrophy in Swedish Vallhund Dogs, PLoS ONE 9 (9): e106610.
Pembroke Welsh Corgis can be afflicted with several eye problems including, cataracts,
Progressive Retinal Atrophy which causes eventual blindness, and Retinal Dysplasia, which causes abnormal development of the retina and can lead to blindness also.
For example Labrador Retrievers can be affected
by Progressive retinal atrophy and Elbow / Hip Dysplasia and Dalmatians can be affected by Hyperuricosuria which causes stones in the bladder and sometimes kidneys.
Eye diseases are a concern in American Eskimo Dogs, especially cataracts, and
also progressive retinal atrophy, which occurs at 2 - 6 years old and always progresses to blindness.
Structure is controlled by genes that affect bones, muscles, tendons, ligaments, and growth rate, and health depends on gene interaction as simple as that
governing progressive retinal atrophy (the dog either has it or he doesn't; there's no halfway) or as complex as that influencing various autoimmune diseases, seizures, or various circulatory defects.
Common health issues: hip dysplasia, epilepsy,
progressive retinal atrophy Aussiepoo / Aussiedoodle Breed History The Aussiepoo / Aussiedoodle breed is a cross between a purebred -LSB-...]
In the 1990's we discovered that some popular studs (without CERF eye exam clearances) were passing
on Progressive Retinal Atrophy (PRA) to their puppies.
The ERG can detect
early Progressive Retinal Atrophy (PRA) before the disease is apparent in a visual exam of the retina or before clients notice nyctalopia, or night blindness.
But problems like hip dysplasia and
progressive retinal atrophy rarely show symptoms until the dog is into adulthood, so those raising designer dogs in puppy mills may not be checking the long - term health of the offspring, which means the recessive genes aren't necessarily getting weeded out.

Today we are going to look
at progressive retinal atrophy (PRA) in dogs, find out what PRA clear means and look at how PRA testing might affect your puppy.
January 1, 2013 New Grant To Study PRA Approved The Tibetan Terrier Health and Welfare Foundation has announced the approval of a $ 20,000 grant to Dr. Gary Johnson from University of Missouri to further
study Progressive Retinal Atrophy in Tibetan Terriers.
PKHA became extremely rare in Basenjis — a breed with an already tight gene pool — but formerly uncommon late -
onset Progressive Retinal Atrophy (PRA) and Fanconi's Disease, a lethal kidney ailment, both became prevalent.
Other signs of
progressive retinal atrophy involve changes in reflectivity and appearance of a structure behind the retina called the Tapetum that can be observed on a veterinary eye exam.
Alaskan Malamutes, Siberian Huskies, Samoyeds, Bichon Frise, and more than 60 other purebred dogs suffer from inherited forms of cataracts,
while progressive retinal atrophy, a common cause of blindness in purebreds, is particularly a problem in Old English Sheepdogs and Papillons.
Now, in a series of recent studies, scientists at the University of Missouri are using whole genome sequencing through the 99 Lives Cat Genome Sequencing Consortium to identify genetic variants that cause rare diseases, such
as progressive retinal atrophy and Niemann - Pick type 1, a fatal disorder in domestic cats.
