Mika

Pekingese

“Our precious girl is 8 yrs now . Mika has IVDD in her back (degenerative disc issues) and it is managed by conservative care (no surgery) . “Dodger’s List” forum on Facebook and website was a lifesaver for advice/education! Highly recommend! We just have to be super careful with her (no steps!) She’s a very fussy, growly girl who HATES to have her nails clipped or her mouth touched . She loves naps , clementine oranges, baked sweet potatoes, broccoli , homemade peanut butter pumpkin biscuits.”

Health Summary

danger icon

Mika is at increased risk for one genetic health condition.

And inherited one variant that you should learn more about.

Intervertebral Disc Disease (Type I)

danger icon

Mika inherited both copies of the variant we tested

How to interpret this result

Mika has two copies of an FGF4 retrogene on chromosome 12. In some breeds such as Beagles, Cocker Spaniels, and Dachshunds (among others) this variant is found in nearly all dogs. While those breeds are known to have an elevated risk of IVDD, many dogs in those breeds never develop IVDD. For mixed breed dogs and purebreds of other breeds where this variant is not as common, risk for Type I IVDD is greater for individuals with this variant than for similar dogs.

What is Intervertebral Disc Disease (Type I)?

Type I Intervertebral Disc Disease (IVDD) is a back/spine issue that 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. This pressure on the spinal cord causes neurologic signs which can range from a wobbly gait to impairment of movement. Chondrodystrophy (CDDY) refers to the relative proportion between a dog’s legs and body, wherein the legs are shorter and the body longer. There are multiple different variants that can cause a markedly chondrodystrophic appearance as observed in Dachshunds and Corgis. However, this particular variant is the only one known to also increase the risk for IVDD.

Oculocutaneous Albinism, OCA

warn icon

Mika inherited one copy of the variant we tested

What does this result mean?

This variant should not impact Mika’s health. This variant is inherited in an autosomal recessive manner, meaning that a dog needs two copies of the variant to show signs of this condition. Mika is unlikely to develop this condition due to this variant because she only has one copy of the variant.

What is Oculocutaneous Albinism, OCA?

Caused by a failure of melanin synthesis, oculocutaneous albinism (OCA) is characterized by lack of pigment of the eyes, skin, and hair.

Through Mika’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

Mika’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.

C7/10

Mika’s Haplotype

Part of the C1 haplogroup, this haplotype occurs most commonly in Pekingese, Boston Terriers, and Rat Terriers.

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