Cholesterol Deficiency (Holstein) R609

72,00 €

Background

Cholesterol deficiency (CD) is an autosomal recessive inherited genetic defect in Holstein cattle, which has been recently reported to influence the rearing success of calves. The affected animals show unresponsive diarrhea accompanied by hypocholesterolemia and usually die within the first weeks or months of life. Due to the identified gene mutation, homozygous affected calves are lacking an important element for lipid uptake in small intestine and liver. These findings explain that young calves die within a period of days to months after birth as a consequence of the onset of diarrhea. The responsible gene mutation was distributed worldwide by the Canadian Holstein sire Maughlin Storm born in 1991 and its progeny.

Test specific information

-

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 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 is present in the entire body, but causes main effects in the internal organs such as stomach, intestinal tract, liver and / or kidneys. In a number of cases, the disease affects one major internal organ.

Breed dependence

This DNA test is available for the following breeds: Holstein.

Sample type

For this DNA test we accept the following materials: Blood EDTA, Blood Heparin, Tissue, Semen, Hair. 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.
