Stargardt Disease in Labrador Retrievers

Stargardt disease is a degenerative eye disorder resulting from the progressive loss of the photoreceptor cells that are responsible for sensing light. Affected dogs show a decline in vision with age but appear to retain some vision throughout their life.

Intensity Dilution

The intensity coat color gene variant causes an extreme dilution of phaeomelanin (red or yellow pigment), resulting in a cream to white coat in dogs.

Parentage/Genetic Marker Report

This DNA-based parentage test uses microsatellite marker analysis to compare the DNA profile of an offspring to the profiles of possible parents.

Canine Genetic Diversity

The Veterinary Genetics Laboratory (VGL), in collaboration with Dr. Niels C. Pedersen and staff, has developed a panel of short tandem repeat (STR) markers that will determine genetic diversity across the genome and in the Dog Leukocyte Antigen (DLA) class I and II regions. This test panel is useful to breeders who wish to track and increase genetic diversity of their breed as a long term goal. Please note, this test will not identify breed.

Pyruvate Kinase Deficiency (PKDef) in Labrador Retrievers

Pyruvate kinase deficiency in Labrador Retrievers is a chronic, severe hemolytic anemia caused by defective production of the enzyme pyruvate kinase. Signs in affected dogs may include lethargy, low exercise tolerance, and fatigue.
