Health Summary

warn icon

Simba inherited one variant that you should learn more about.

And one variant that you should tell your vet about.

Degenerative Myelopathy, DM

warn icon

Simba inherited one copy of the variant we tested

What does this result mean?

This variant should not impact Simba’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. Simba is unlikely to develop this condition due to this variant because he only has one copy of the variant.

What is Degenerative Myelopathy, DM?

The dog equivalent of Amyotrophic Lateral Sclerosis, or Lou Gehrig’s disease, DM is a progressive degenerative disorder of the spinal cord. Because the nerves that control the hind limbs are the first to degenerate, the most common clinical signs are back muscle wasting and gait abnormalities.

ALT Activity

warn icon

Simba inherited one copy of the variant we tested

Why is this important to your vet?

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

A4

Simba’s Haplogroup

The A4 maternal lineage is fairly rare. It is found in Cocker Spaniels, but A4 is also represented well among East Asian breeds including the Chinese Crested Dog, Shar-Pei and Shih Tzu. Moving away from Asia, it is also found among Chihuahuas (a very old breed!) and village dogs in Peru. This may be a lineage that moved into Western breeds because of their owners' tendencies to mix them up with Eastern breeds in the early modern period.

A453

Simba’s Haplotype

Part of the A4 haplogroup, the A453 haplotype occurs most commonly in Lhasa Apsos and Chihuahuas.

The popular Chihuahua breed descends from the A4 maternal line.

B

Simba’s Haplogroup

B is a relatively rare paternal line that has only recently started to expand. The dominant lineage among the ancient Shih Tzu breed, it is also found among Tibetan Spaniels. Outside of these two breeds, B seems to be a particularly common paternal line among the village dogs of India and Southeast Asia, though it is found as far afield as Africa and down into Oceania. Considering that it is particularly diverse in northern India, it could be that this lineage hung out mostly in South Asia after the expansion of domestic dogs from Central Asia. Because it is present in Mongolia as well, it may not be surprising that ancient East Asian dog breeds are also part of this lineage. Alternatively, perhaps males representing this lineage headed north out of southern Eurasia, which eventually gave rise to the Shih Tzu and may have inspired stylistic representations of lions in ancient China!

H15.7

Simba’s Haplotype

Part of the B haplogroup, this haplotype has been found in village dogs in Qatar and India. Unlike most other haplotypes within the B haplogroup, we do see this in a select few breed dogs. Specifically, it occurs in the Shih Tzu and Tibetan Spaniel.

The B Haplogroup is most commonly found the adorable Shih Tzu breed.
