H705 Collie Eye Anomaly (CEA_CH, partnerlab)

Background

Collies share Collie Eye Anomaly (CEA) with several other breeds. CEA is technically known as Choroidal Hypoplasia (CH). It is an eye disorder that causes abnormal development of the choroid - an important layer of tissue under the retina of the eye. The primary problem is choroidal hypoplasia (CH). There is under-development (hypoplasia) of the eye tissue layer called the choroid. Since the choroid layer does not develop normally from the start, the primary abnormality can be diagnosed at a very young age. The symptoms and signs can vary greatly among affected dogs within one breed, between parent and offspring and even within a litter. This creates a difficult situation for the breeder.

Test specific information

This test is patented in certain countries. We offer our clients two options for this test because we are not allowed to perform the test in our laboratory.
Firstly, the test can be ordered through a licensee of the patent owner.
As a second option, the test can be forwarded to a partner laboratory in non-patented territory.

Between these two options, a price difference is in place which is caused by the royalties costs on the test. The tests performed by both labs are technical identical.

Age

Symptoms will develop at a young age. Within a few hours to a maximum of several weeks after birth, the characteristics that go with these genetic effects will become visible.

Throughput

Normally the result can be expected within 20 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: Border Collie, Bearded Collie, Hokkaido, Nova Scotia Duck Tolling Retriever, Rough Collies, Sheepdogs, Smooth Collies, Lancashire Heeler, Australian Shepherd. Additional information is available in the Frequently Asked Questions (FAQ).

Sample type

For this DNA test we accept the following materials: Blood EDTA, Blood Heparin, Semen, Swab, Tissue. Please contact Dr. Van Haeringen Laboratorium 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.
