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.

Turnaround time

The Turnaround Time (TAT) depends on various factors, such as the shipment time of your sample to the test location, the test method(s) and whether the tests are performed completely or partially by a Partner Lab or Patent owner.

The TAT of tests performed at our facilities is normally 10 working days after receipt of the sample at the testing laboratory (VHL, VHP or Certagen). For tests performed by a Partner Laboratory (so-called "partner lab test") or patent owner, the TAT is at least 20 working days after receipt of your sample. Because the shipment time to our Partner Labs or patent owner may vary due to factors we cannot influence, the mentioned 20 working days are therefore an estimate.

Sometimes it is necessary to re-run your sample. We call this a retest. In that case, the TAT will of course be extended.

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.
