Health Summary

Rhett Butler is at increased risk for one genetic health condition.

Multiple Drug Sensitivity

Rhett Butler inherited one copy of the variant we tested

What does this result mean?

Our research indicates that this genetic variant is likely to increase the risk that Rhett Butler will develop this disease.

Scientific Basis

Research studies for this variant have been based on dogs of other breeds. While dogs with similar breeds to Rhett Butler have not yet been the focus of research studies, our data indicates that Rhett Butler is likely to be at increased risk.

What is Multiple Drug Sensitivity?

Sensitivity to certain classes of drugs, notably the parasiticide ivermectin, as well as certain gastroprotectant and anti-cancer medications, occurs in dogs with a mutation in the ABCB1 gene.

B1

Rhett Butler’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.

B45

Rhett Butler’s Haplotype

Part of the large B1 haplogroup, this haplotype occurs most commonly in Yorkshire Terriers, Doberman Pinschers, Cocker Spaniels, and village dogs in Costa Rica.

Some other Embark dogs with this haplotype:

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

Map

A2b

Rhett Butler’s Haplogroup

A2b appears to have split a few times in succession, which means that some of the Central Asian male ancestors of this lineage went their separate ways before their respective Y chromosomes made their rounds. There is not much diversity in this lineage, meaning that it has only begun to take off recently. Two iconic breeds, the Dachshund and Bloodhound, represent this lineage well. Over half of Rottweilers are A2b, as are the majority of Labrador Retrievers and Cavalier King Charles Spaniels. While A2a is restricted mostly to East Asia, this paternal line is also found among European breeds.

Hc.17

Rhett Butler’s Haplotype

Part of the A2b haplogroup, this haplotype occurs most frequently in mixed breed dogs.

Some other Embark dogs with this haplotype:

A2b is found in the Daschund breed.
