In animals, karyotyping is performed to identify chromosomal abnormalities. These abnormalities reduce the fertility because the chromosomes do not match in new embryos. A new translocation originates in one percent of all animals.
In cattle, this specific test identifies a frequent Robertsonian Translocation 1/29 in several breeds. In this particular case, chromosomes 1 and 29 fuse to result in one chromosome instead of two.
Test specific information
Special requirements are in place for karyotyping. Please contact VHL prior to submitting a sample for this test.
The genetic factor is continuously present, and will always be visible.
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
The chromosomal variation is present in the whole body.
For this test samples from all breeds are accepted.
For this DNA test we accept the following materials: Lithium Heparin blood, Sodium Heparin blood. Please contact Dr. Van Haeringen Laboratorium if you wish to submit other material as listed.
The result of a karyotype shows, if a detectable chromosomal abnormality is present.
Chromsomal abnormalities can be inherited to the next generation.
