Health Summary

danger icon

Frost is at increased risk for one genetic health condition.

And inherited one variant that you should learn more about.

Dilated Cardiomyopathy, DCM2

danger icon

Frost inherited one copy of the variant we tested

How to interpret this result

Frost has one copy of a variant in the TTN gene associated with increased risk for DCM in the American Doberman Pinscher. This variant, also referred to as DCM2, is inherited in a dominant manner, meaning having one or two copies of this variant is thought to confer the same amount of risk. However, the variant is thought to have incomplete penetrance: That is, not all dogs with this variant will ultimately show signs of DCM. Moreover, the impact of this variant in other breeds of dog besides the Doberman has yet to be fully understood. However, if your veterinarian thinks Frost shows signs of having DCM based on their diagnostic testing, you now have the opportunity to discuss early treatment. Please consult with your veterinarian regarding a diagnostic and treatment plan for Frost.

What is Dilated Cardiomyopathy, DCM2?

DCM is the most common acquired heart disease of adult dogs. The heart has two heavily muscled ventricles that pump blood away from the heart. This disease causes progressive weakening of the ventricles by reducing the muscle mass, which causes the ventricles to dilate. Dilated ventricles do not contract and circulate oxygenated blood well, which eventually leads to heart failure.

ALT Activity

warn icon

Frost inherited one copy of the variant we tested

Why is this important to your vet?

Frost has one copy of a variant associated with reduced ALT activity as measured on veterinary blood chemistry panels. Please inform your veterinarian that Frost has this genotype, as ALT is often used as an indicator of liver health and Frost is likely to have a lower than average resting ALT activity. As such, an increase in Frost’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 Frost’s mitochondrial DNA we can trace her mother’s ancestry back to where dogs and people first became friends. This map helps you visualize the routes that her ancestors took to your home. Their story is described below the map.

Haplogroup

A1d

Haplotype

A11a/419

Map

A1d

I'll Freeze Your Heart’s Haplogroup

This female lineage can be traced back about 15,000 years to some of the original Central Asian wolves that were domesticated into modern dogs. The early females that represent this lineage were likely taken into Eurasia, where they spread rapidly. As a result, many modern breed and village dogs from the Americas, Africa, through Asia and down into Oceania belong to this group! This widespread lineage is not limited to a select few breeds, but the majority of Rottweilers, Afghan Hounds and Wirehaired Pointing Griffons belong to it. It is also the most common female lineage among Papillons, Samoyeds and Jack Russell Terriers. Considering its occurrence in breeds as diverse as Afghan Hounds and Samoyeds, some of this is likely ancient variation. But because of its presence in many modern European breeds, much of its diversity likely can be attributed to much more recent breeding.

A11a/419

I'll Freeze Your Heart’s Haplotype

Part of the A1d haplogroup, this haplotype occurs most frequently in Yorkshire Terriers, Old English Sheepdogs, and Miniature Schnauzers.

The vast majority of Rottweilers have the A1d haplogroup.

The Paternal Haplotype reveals a dog’s deep ancestral lineage, stretching back thousands of years to the original domestication of dogs.

Are you looking for information on the breeds that Frost inherited from her mom and dad? Check out her breed breakdown and family tree.

Paternal Haplotype is determined by looking at a dog’s Y-chromosome—but not all dogs have Y-chromosomes!

Why can’t we show Paternal Haplotype results for female dogs?

All dogs have two sex chromosomes. Female dogs have two X-chromosomes (XX) and male dogs have one X-chromosome and one Y-chromosome (XY). When having offspring, female (XX) dogs always pass an X-chromosome to their puppy. Male (XY) dogs can pass either an X or a Y-chromosome—if the puppy receives an X-chromosome from its father then it will be a female (XX) puppy and if it receives a Y-chromosome then it will be a male (XY) puppy. As you can see, Y-chromosomes are passed down from a male dog only to its male offspring.

Since Frost is a female (XX) dog, she has no Y-chromosome for us to analyze and determine a paternal haplotype.
