Background
HYPP was recognized and described in the 1980s. The development of a diagnostic test illustrates the power of knowledge in other species (including humans). For this particular disease, which has identical characteristics between humans and horses, human research directly led to the identification of a mutation in horses with HYPP. Horses affected by HYPP have severe muscle problems following exercise. Even horses which are heterozygous may show symptoms of the disease.
Test specific information
-
Age
The genetic factor is continuously present, and will always be visible.
Throughput
Normally the result can be expected within 15 working days. This turn-around-time starts when both the sample and the fully filled-out and signed submission form have been received.
Location of disease or trait
The disease is present in muscle. Depending on the effect, degeneration of muscle may take place. Alternatively, recovery following exercise may be deteriorated.
Breed dependence
This DNA test is available for the following breeds: Quarter Horse.
Sample type
For this DNA test we accept the following materials: Hair, Semen, Blood EDTA, Blood Heparin, Tissue. Please contact PharmaDNA if you wish to submit other material as listed.
Result
An animal can be free and has in that situation two healthy alleles. When used in breeding this animal will not become ill due to the disease. It cannot spread the disease in the population.An animal can be carrier and has in that situation one healthy and one disease allele. When used in breeding 50 percent of the offspring will receive the disease allele. Carriers will not become ill.An animal can be affected and has in that situation two disease alleles. When used in breeding all offspring will also receive the disease allele. Affected will become ill.
Inheritance
This genetic factor is inherited in an autosomal, dominant, mode. This means, that the individual can be free of the mutation (homozygote normal), affected (homozygous affected) or carrier (heterozygous affected). Both carriers and affected individuals will show symptoms of the mutation.
