Health Summary

warn icon

Kiwi inherited one variant that you should learn more about.

Proportionate Dwarfism

warn icon

Kiwi inherited both copies of the variant we tested

What does this result mean?

We do not know whether this increases the risk that Kiwi will develop Proportionate Dwarfism.

Scientific Basis

Research studies for this variant have been based on dogs of other breeds. Not enough dogs with Kiwi's breed have been studied to know whether or not this variant will increase Kiwi's risk of developing this disease.

Impact on Breeding

Research into the clinical impact of this variant is ongoing. We recommend tracking this genetic result and incidence of Proportionate Dwarfism in your breeding program and related dogs.

What is Proportionate Dwarfism?

Embark’s data suggests that this variant in the GH1 gene may contribute to a smaller body size. The original publication predicts this is due to a growth hormone (GH) deficiency. However, adult body size is influenced by several different genetic variants. Other changes noted by the publication, including retained baby teeth, persistent puppy-like coats, and low blood sugar have been occasionally reported by owners of dogs with two copies of this variant. These changes may or may not be associated with this variant.

Through Kiwi’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.

C1

Jersey’s Tiny Tails Tell Her About It’s Haplogroup

Congratulations, C1 is a very exotic female lineage! It is more closely associated with maternal lineages found in wolves, foxes and jackals than with other dog lineages. So it seems dogs in this group have a common male dog ancestor who, many thousands of years ago, mated with a female wolf! This is not a common lineage in any breed, though a good number of German Shepherds and Doberman Pinchers are C1. It is also found in breeds as diverse as Peruvian Inca Orchids and Pekingese; it is rarely found amongst Labrador Retrievers, Border Collies, Siberian Huskies, or Cocker Spaniels. Despite its fascinating origins, it is widely distributed around the globe, and even shows up frequently among Peruvian village dogs. It almost certainly survived at low frequency in Europe for millennia and then was dispersed outside of Europe by colonialism, though not as successfully as some other lineages.

C39

Jersey’s Tiny Tails Tell Her About It’s Haplotype

Part of the C1 haplogroup, this haplotype occurs most frequently in Pomerianians and Xoloitzcuintli.

The C1 maternal line is commonly found in Jackals.

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 Kiwi inherited from her mom and dad? Check out her breed breakdown.

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