Charlie

Shih Tzu

“Charlie was adopted from a shelter in LA, CA at 2.5 years old. The shelter thinks he was born in August, 2008. He lost his eye due to glaucoma (hereditary-didn't show up in genetics) in June, 2018. He also has arthritis, but never shows his pain. He is VERY obedient (anything for a treat!), loyal, independent, only barks when someone comes to the door, and loves to lick! He adores walks & all the smells, being around people & other dogs. We'd love to hear from his relatives!”

Health Summary

Charlie is at increased risk for one genetic health condition.

Intervertebral Disc Disease (Type I)

Charlie inherited one copy of the variant we tested

How to interpret this result

Charlie has one copy of an FGF4 retrogene on chromosome 12 and is at increased risk for Type I IVDD. Charlie would also be expected to have an intermediate chondrodystrophic phenotype (slightly short legs relative to body length). Please consult with your veterinarian to discuss preventative and monitoring measures for Charlie.

What is Intervertebral Disc Disease (Type I)?

Chondrodystrophy (CDDY) refers to the relative proportions between dogs' legs and body. Dogs with chondrodystrophy have shorter legs and a longer body. An extreme example of this is a Dachshund or Corgi. Type I Intervertebral Disc Disease (IVDD) 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. The pressure on the spinal cord causes neurologic symptoms.

Through Charlie’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

Charlie’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.

B1/13

Charlie’s Haplotype

Part of the large B1 haplogroup, this common haplotype occurs in Shih Tzus, Tibetan Spaniels, Maltese, and village dogs throughout the world including Central and South America, South Asia, and the South Pacific.

Some other Embark dogs with this haplotype:

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

B

Charlie’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

Charlie’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.
