R535



Background

Six proteins in milk are responsible for about 90% of the proteins present in milk (Alfa S1 casein, Alfa S2 casein, Beta casein, Kappa casein, Alpha lactalbumin and Beta lactoglobulin). Four of these are caseins, two of them are whey-proteins. The test for Beta casein detects the most common genetic variants in Beta casein.

Test specific information

Within our organization two versions of the test for Beta casein are available. We offer a simple (test code R534) and advanced version (test code R535).Within the advanced version, four variants of Beta casein are identified. These four, most common, types of Beta casein are A1, A2, A3, B, C, I and H2.In international genotyping for Beta casein, a simplified version of the test is used. This particular test is based on a straightforward identification using one mutation. This mutation is based in codon 67 and results in the groups A1 and A2.

Age

This test provides information on one or more milk components. The genetic constitution of an animal remains the same during life.

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

Milk is present in the udder.

Breed dependence

For this test samples from all breeds are accepted.

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

Milk quality is based on many genetic factors. For each factor, a separate test result will be returned.

Inheritance

Various genetic factors influencing milk quality are inherited in a dominant or recessive mode. Milk quality is influenced by a large number of genetic factors.
