B383 Pigeon Performance Gene GSR Expression

Background

In pigeons, the protein glutathione-disulfide reductase (encoded by the gene GSR) plays an important role in the bird’s ability to sense magnetic fields. Research has linked a mutation that increases the expression of GSR to improved navigation and homing ability in pigeons. Approximately 80% of pigeons bred for homing are homozygous for the mutation. The GSR mutation is therefore a useful performance marker.

Birds affected by the GSR mutation show increased levels of GSR expression in organs such as the wattle and eyes. This leads to an increased sensitivity to magnetic fields, and therefore to an improvement in homing ability.

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

Breed dependence

For this test samples from all breeds are accepted.

Sample type

For this DNA test we accept the following materials: Feather, Blood EDTA, Blood Heparin, Tissue. Please contact Dr. Van Haeringen Laboratorium if you wish to submit other material as listed.

Result

The disease is of multifactorial origin, which means that the symptoms are a result of the combination of genetic factors as well as the environment.

For each genetic factor of a multifactorial disease, a favourable allele exists. The results for this allele are inidcated as 'Normal'. Animals carrying one copy of the undesirable genetic variant are indicated as 'Carrier', whereas animals carrying two copies of the undesirable genetic variant are indicated as 'Affected'.

Inheritance

The disease is of multifactorial origin, which means that the symptoms are a combination of genetic factors as well as the environment.
