Health Summary

warn icon

Mira has one variant that you should let your vet know about.

ALT Activity

warn icon

Mira inherited one copy of the variant we tested

Why is this important to your vet?

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

C2

SFC's Sandypaws Mira-by-the-Sea’s Haplogroup

C2 is a very old female lineage found more commonly among English Setters, English Bulldogs, and American Eskimo Dogs. We also see C2 in village dogs in South Asia. Rather than having a few characteristic breeds representing this lineage particularly well, it is present in a few uncommon individuals of many different breeds. Unlike some European breed lineages that have seen skyrocketing popularity along the path to the modern dogs we see today, C2 tends to reflect the deep history of man's best friend.

C42/54/55

SFC's Sandypaws Mira-by-the-Sea’s Haplotype

Part of the C2 haplogroup, this haplotype occurs most frequently in mixed breed dogs.

You can often find his haplogroup in the lovable English Bulldog.

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