In 2009 researchers from the university of Liege (Belgium) have identified a genetic test in close collaboration with CRV, the Dutch Animal Health Service and the University of Copenhagen. In 2011, the mutation was identified by the Belgian and Danish researchers.
As of June 2011, VHL has become a licensee for the mutation based test.
A large proportion of homozygous mutant calves die during pregnancy. If affected dead calves are born, severe malformations are present.
Test specific information
This disease leads to a reduction in the number of liveborn offspring. Depending on the disease, affected individuals may be stillborn or aborted.
Turn Around Time
The turn-around-time of a test depends to a large extent on the logistics of sample transportation to the laboratory. After receiving the sample at the test location, you can normally expect the result within 10 working days. A longer delivery time applies to tests carried out by a Partner Lab.
Location of disease or trait
This disease affects the formation of bone as well as the skeletal development.
For this test samples from all breeds are accepted.
For this DNA test we accept the following materials: Hair, Semen, Blood EDTA, Blood Heparin, Tissue, Swab. Please contact Dr. Van Haeringen Laboratorium if you wish to submit other material as listed.
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.
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.
