DNA Screening Smooth Collies - MDR1
The following Smooth Collies have been DNA tested for Multi-drug resistance MDR1.
The test distinguishes between clear, carrier and affected dogs. Clear dogs have no copies of the mutant gene responsible for the condition and will neither develop the condition nor pass the gene on to their offspring. Carrier dogs have one copy of the normal gene and one copy of the mutant gene; they will not develop the condition, but will pass a mutant gene on to approximately half of their offspring. Affected dogs have two copies of the mutant gene that causes the condition and therefore, will react adversely to certain drugs.
