Background

Progressive Retinal Atrophy (PRA) refers to a group of inherited blinding canine diseases. PRA is seen in many pure breeds, although the exact genetic cause is known for only a few. At present, about 10 genetic PRA forms are known to affect in several dozen of breeds. In some breeds, the DNA-test is 100 percent conclusive, but in other breeds the test is based on indirect information. Research is currently going on to improve the test.

Test specific information

-

Age

-

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

This disease mainly affects vision, and may result in blindness.

Breed dependence

This DNA test is available for the following breeds: Golden Retriever, Labrador Retriever.

Sample type

For this DNA test we accept the following materials: Blood EDTA, Semen, Swab, Tissue, Blood Heparin. 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, recessive, mode. This means, that the individual can be free of the disease (homozygote normal), affected (homozygous affected) or carrier (heterozygous). Carriers may spread the mutation in a population without showing symptoms themselves. Because of this, it is extremely important to identify carriers correctly to prevent spreading of a mutation.
