Health Summary

Rhodie inherited one variant that you should learn more about.

And one variant that you should tell your vet about.

Progressive Retinal Atrophy - crd4/cord1

Rhodie inherited one copy of the variant we tested

What does this result mean?

This result should not impact Rhodie’s health but it could have consequences for siblings or other related dogs if they inherited two copies of the variant. We recommend discussing this result with their owners or breeders if you are in contact.

Impact on Breeding

This result should be taken into account as part of your breeding program. Rhodie will pass this variant to ~50% of his offspring.

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

Rhodie inherited one copy of the variant we tested

Why is this important to your vet?

Rhodie has one copy of a variant associated with reduced ALT activity as measured on veterinary blood chemistry panels. Please inform your veterinarian that Rhodie has this genotype, as ALT is often used as an indicator of liver health and Rhodie is likely to have a lower than average resting ALT activity. As such, an increase in Rhodie’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 Rhodie’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

Rhodie’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.

B1c

Rhodie’s Haplotype

Part of the large B1 haplogroup, we have detected this haplotype in Mexico and Lebanon village dogs. Among the 12 breeds that we have spotted this haplotype in, it occurs most frequently in Border Collies, Australian Shepherd Dogs, and West Highland white 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 Rhodie’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.

A2b

Haplotype

Hc.9

Map

A2b

Rhodie’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.9

Rhodie’s Haplotype

Part of the A2b haplogroup, this haplotype is found in village dogs spanning South America, Africa, and the South Pacific. Among the 11 breeds we have spotted it in, the most frequent occurrences are in Dachshund, Bloodhound, American Eskimo Dog, and Jack Russell Terrier.

Some other Embark dogs with this haplotype:

A2b is found in the Daschund breed.
