Health Summary

Rollo is at increased risk for one genetic health condition.

And inherited one variant that you should learn more about.

Intervertebral Disc Disease (Type I)

Rollo inherited one copy of the variant we tested

How to interpret this result

Rollo 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

Rollo inherited one copy of the variant we tested

What does this result mean?

This result does not impact your dog’s health. It could have consequences for siblings or other family members, and you should let them know if you are in contact with them.

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.

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

B1

Rollo’s Haplogroup

B1 is the second most common maternal lineage in breeds of European or American origin. It is the female line of the majority of Golden Retrievers, Basset Hounds, and Shih Tzus, and about half of Beagles, Pekingese and Toy Poodles. This lineage is also somewhat common among village dogs that carry distinct ancestry from these breeds. We know this is a result of B1 dogs being common amongst the European dogs that their conquering owners brought around the world, because nowhere on earth is it a very common lineage in village dogs. It even enables us to trace the path of (human) colonization: Because most Bichons are B1 and Bichons are popular in Spanish culture, B1 is now fairly common among village dogs in Latin America.

B84

Rollo’s Haplotype

Part of the large B1 haplogroup, this haplotype occurs most frequently in Golden Retrievers, Beagles, and Staffordshire Terriers.

Some other Embark dogs with this haplotype:

The B1 haplogroup can be found in village dogs like the Peruvian Village Dog, pictured above.

Through Rollo’s Y-chromosome we can trace his father’s ancestry back to where dogs and people first became friends. This map helps you visualize the routes that his ancestors took to your home. Their story is described below the map.

Haplotype

Map

D

Rollo’s Haplogroup

The D paternal lineage is very common in well-known populations of dogs. Breeds belonging to the D lineage likely have direct male ancestors that can be traced all the way back to the origin of domestic dogs themselves! One popular breed that commonly sports a D lineage is the Boxer. Boxers were developed in the late 19th century from Mastiff dogs, so it is no surprise that D is well represented among Mastiffs, Bulldogs, as well as Terriers. Intriguingly, D is also found among Lhasa Apsos, an ancient Tibetan breed, and Afghan Hounds. While the presence of this lineage in Polynesia or the New World can be chalked up to interbreeding with European dogs brought during voyages of discovery or later settlement, D is also well represented among village dog populations in the Middle East and Africa. If the fact that we find dogs bearing a D lineage in the Middle East (not to mention the large amount of diversity among Middle Eastern D lineage males) is any indication of ancient residence in that region, then the presence among Oceanian village dogs is peculiar. Rather, it may be that D is part of a broader Eurasian group of ancient paternal lineages which disappeared from the eastern portion of its original range, persisting in the island of New Guinea as well as West Asia and Africa. With the rise of Mastiff breeds, the D lineage received a new life as it became common among many types of working dogs.

H10.1/Hd.4

Rollo’s Haplotype

Part of the D haplogroup, this haplotype occurs most frequently in mixed breed dogs.

The D paternal lineage is common in Boxers.
