R830 Double Muscling - Myostatin - 9 DNA-variants


The Myostatin gene is analysed for nine different variants, even though some may not be found in all breeds. Six variants are classified as disruptive. These cause muscle hypertrophy (double-muscling), larger birth weights, increased dystocia and enhanced tenderness. Three myostatin variants are referred to as missense, and will increase muscularity and reduce external and intramuscular fat, with no change in birth weight.

Disruptive variants are:

Missense variants are:

Test specific information

Myostatin results are reported as:
0 None of the nine possible variants are present
1, Variant One copy of the listed variant is present
2, Variant two copies of the listed variant are present


The genetic factor is continuously present, and affects the meatquality.

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

Meat quality can be assessed in the meat.

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, Swab. Please contact Dr. Van Haeringen Laboratorium if you wish to submit other material as listed.


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


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