Alanine Aminotransferase Activity (GPT)
Iris's baseline ALT level may be Low Normal
Iris has two copies of a variant in the GPT gene and is likely to have a lower than average baseline ALT activity. ALT is a commonly used measure of liver health on routine veterinary blood chemistry panels. As such, your veterinarian may want to watch for changes in Iris's ALT activity above their current, healthy, ALT activity. As an increase above Iris’s baseline ALT activity could be evidence of liver damage, even if it is within normal limits by standard ALT reference ranges.
Alanine aminotransferase (ALT) is a clinical tool that can be used by veterinarians to better monitor liver health. This result is not associated with liver disease. ALT is one of several values veterinarians measure on routine blood work to evaluate the liver. It is a naturally occurring enzyme located in liver cells that helps break down protein. When the liver is damaged or inflamed, ALT is released into the bloodstream.
Genetic testing is the only way to provide your veterinarian with this clinical tool.
Veterinarians may recommend blood work to establish a baseline ALT value for healthy dogs with one or two copies of this variant.
If Iris inherited any of the variants that we tested, they will be listed at the top of the Health Report section, along with a description of how to interpret this result. We also include all of the variants that we tested Iris for that we did not detect the risk variant for.A genetic test is not a diagnosis
This genetic test does not diagnose a disease. Please talk to your vet about your dog’s genetic results, or if you think that your pet may have a health condition or disease.
Iris inherited one variant that you should learn more about.
Progressive Retinal Atrophy, prcd
Breed-Relevant Genetic Conditions 8 variants not detected
Additional Genetic Conditions 172 variants not detected
Progressive Retinal Atrophy, prcd (PRCD Exon 1)
CLOVERS IRIS OF OUR EYE inherited one copy of the variant we tested
This result should not impact Iris’s health but it could have consequences for siblings or other related dogs if they inherited two copies of the variant. We recommend discussing this result with their owners or breeders if you are in contact.
Your dog carries this variant and will pass it on to ~50% of her offspring.
PRA-prcd is a retinal disease that causes progressive, non-painful vision loss. The retina contains cells, called photoreceptors, that collect information about light and send signals to the brain. There are two types of photoreceptors: rods, for night vision and movement, and cones, for day vision and color. This type of PRA leads to early loss of rod cells, leading to night blindness before day blindness.
The age affected dogs will first show signs of visual impairment varies by breed. However, most begin showing clinical signs in early adulthood.
Veterinarians use a focused light to examine the pupils. In affected dogs, the pupils will appear more dilated and slower to contract. Your vet may also use a lens to visualize the retina at the back of the eye to look for changes in the optic nerve or blood vessels. You may be referred to a veterinary ophthalmologist for a definitive diagnosis.
Currently, there is no definitive treatment for PRA. Supplements, including antioxidants, have been proposed for management of the disease, but have not been scientifically proven effective.
- Careful monitoring by your veterinarian will be required for the rest of your affected dog's life as secondary complications, including cataracts, can develop.
- With blind dogs, keeping furniture in the same location, making sure they are on a leash in unfamiliar territory, and training them to understand verbal commands are some of the ways to help them at home.
Iris did not have the variants that we tested for, that are relevant to her breed:
Iris did not have the variants that we tested for, in the following conditions that the potential effect on dogs with Iris’s breed may not yet be known.
Coefficient of Inbreeding (COI)
- Genetic Result:
Our genetic COI measures the proportion of your dog’s genome (her genes) where the genes on the mother’s side are identical by descent to those on the father’s side. The higher your dog’s coefficient of inbreeding (the percentage), the more inbred your dog is.
Your Dog’s COI
This graph represents where your dog’s inbreeding levels fall on a scale compared to both dogs with a similar breed makeup to her (the blue bars) and all purebred dogs (the grey line).
More on the Science
Embark scientists, along with our research partners at Cornell University, have shown the impact of inbreeding on longevity and fertility and developed a state-of-the-art, peer-reviewed method for accurately measuring COI and predicting average COI in litters.
