Our algorithms predict this is the most likely family tree to explain Nacho’s breed mix, but this family tree may not be the only possible one.

Health Summary

Nacho is at increased risk for one genetic health condition.

Intervertebral Disc Disease (Type I)

Nacho inherited one copy of the variant we tested

How to interpret this result

Nacho 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.

B1

Chimera's Nacho the Gargarean’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.

B81

Chimera's Nacho the Gargarean’s Haplotype

Part of the large B1 haplogroup, this haplotype occurs most frequently in Shih Tzus, Chihuahuas, and Poodles.

Some other Embark dogs with this haplotype:

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

B

Chimera's Nacho the Gargarean’s Haplogroup

B is a relatively rare paternal line that has only recently started to expand. The dominant lineage among the ancient Shih Tzu breed, it is also found among Tibetan Spaniels. Outside of these two breeds, B seems to be a particularly common paternal line among the village dogs of India and Southeast Asia, though it is found as far afield as Africa and down into Oceania. Considering that it is particularly diverse in northern India, it could be that this lineage hung out mostly in South Asia after the expansion of domestic dogs from Central Asia. Because it is present in Mongolia as well, it may not be surprising that ancient East Asian dog breeds are also part of this lineage. Alternatively, perhaps males representing this lineage headed north out of southern Eurasia, which eventually gave rise to the Shih Tzu and may have inspired stylistic representations of lions in ancient China!

H15.7

Chimera's Nacho the Gargarean’s Haplotype

Part of the B haplogroup, this haplotype has been found in village dogs in Qatar and India. Unlike most other haplotypes within the B haplogroup, we do see this in a select few breed dogs. Specifically, it occurs in the Shih Tzu and Tibetan Spaniel.

Some other Embark dogs with this haplotype:

The B Haplogroup is most commonly found the adorable Shih Tzu breed.
