Abby

Mixed Ancestry

“Abby was rescued at somewhere between eight and ten years old and had to overcome a lot, including severe anxiety and some pre-existing health issues. Nevertheless, she has turned out to be the most intelligent, hilarious, expressive, and loyal dog I have ever met. She is my constant companion, unofficial service dog (no public access, but performs many service dog tasks at home), and best friend.”

Dachshund

The Dachshund, meaning “badger dog” in German, is a lively breed with a friendly personality and a great sense of smell. Known for their long and low bodies, they are spirited hunters that excel in both above and below-ground work. They come in three different coat varieties (smooth, wirehaired or longhaired) and can be miniature or standard size.

Health Summary

danger icon

Abby is at increased risk for one genetic health condition.

And inherited two variants that you should learn more about.

Intervertebral Disc Disease (Type I)

danger icon

Abby inherited one copy of the variant we tested

How to interpret this result

Abby has one copy of an FGF4 retrogene on chromosome 12. In some breeds such as Beagles, Cocker Spaniels, and Dachshunds (among others) this variant is found in nearly all dogs. While those breeds are known to have an elevated risk of IVDD, many dogs in those breeds never develop IVDD. For mixed breed dogs and purebreds of other breeds where this variant is not as common, risk for Type I IVDD is greater for individuals with this variant than for similar dogs.

What is Intervertebral Disc Disease (Type I)?

Type I Intervertebral Disc Disease (IVDD) is a back/spine issue that refers to a health condition affecting the discs that act as cushions between vertebrae. With Type I IVDD, affected dogs can have a disc event where it ruptures or herniates towards the spinal cord. This pressure on the spinal cord causes neurologic signs which can range from a wobbly gait to impairment of movement. Chondrodystrophy (CDDY) refers to the relative proportion between a dog’s legs and body, wherein the legs are shorter and the body longer. There are multiple different variants that can cause a markedly chondrodystrophic appearance as observed in Dachshunds and Corgis. However, this particular variant is the only one known to also increase the risk for IVDD.

Progressive Retinal Atrophy, crd4/cord1

warn icon

Abby inherited one copy of the variant we tested

What does this result mean?

This variant should not impact Abby’s health. This variant is inherited in an autosomal recessive manner, meaning that a dog needs two copies of the variant to show signs of this condition. Abby is unlikely to develop this condition due to this variant because she only has one copy of the variant.

What is Progressive Retinal Atrophy, crd4/cord1?

PRA-CRD4/cord1 is a retinal disease that causes progressive, non-painful vision loss over a 1-2 year period. 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 cone cells, causing day blindness before night blindness.

ALT Activity

warn icon

Abby inherited one copy of the variant we tested

Why is this important to your vet?

Abby has one copy of a variant associated with reduced ALT activity as measured on veterinary blood chemistry panels. Please inform your veterinarian that Abby has this genotype, as ALT is often used as an indicator of liver health and Abby is likely to have a lower than average resting ALT activity. As such, an increase in Abby’s ALT activity could be evidence of liver damage, even if it is within normal limits by standard ALT reference ranges.

What is ALT Activity?

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.

Through Abby’s mitochondrial DNA we can trace her mother’s ancestry back to where dogs and people first became friends. This map helps you visualize the routes that her ancestors took to your home. Their story is described below the map.

A1a

Abby’s Haplogroup

A1a is the most common maternal lineage among Western dogs. This lineage traveled from the site of dog domestication in Central Asia to Europe along with an early dog expansion perhaps 10,000 years ago. It hung around in European village dogs for many millennia. Then, about 300 years ago, some of the prized females in the line were chosen as the founding dogs for several dog breeds. That set in motion a huge expansion of this lineage. It's now the maternal lineage of the overwhelming majority of Mastiffs, Labrador Retrievers and Gordon Setters. About half of Boxers and less than half of Shar-Pei dogs descend from the A1a line. It is also common across the world among village dogs, a legacy of European colonialism.

A381

Abby’s Haplotype

Part of the large A1a haplogroup, this haplotype occurs most frequently in German Shepherd Dogs, Doberman Pinschers, and Dachshunds.

The Paternal Haplotype reveals a dog’s deep ancestral lineage, stretching back thousands of years to the original domestication of dogs.

Are you looking for information on the breeds that Abby inherited from her mom and dad? Check out her breed breakdown and family tree.

Paternal Haplotype is determined by looking at a dog’s Y-chromosome—but not all dogs have Y-chromosomes!

Why can’t we show Paternal Haplotype results for female dogs?

All dogs have two sex chromosomes. Female dogs have two X-chromosomes (XX) and male dogs have one X-chromosome and one Y-chromosome (XY). When having offspring, female (XX) dogs always pass an X-chromosome to their puppy. Male (XY) dogs can pass either an X or a Y-chromosome—if the puppy receives an X-chromosome from its father then it will be a female (XX) puppy and if it receives a Y-chromosome then it will be a male (XY) puppy. As you can see, Y-chromosomes are passed down from a male dog only to its male offspring.

Since Abby is a female (XX) dog, she has no Y-chromosome for us to analyze and determine a paternal haplotype.
