Progressive retinal atrophy rod-cone degeneration 4 (rcd4-PRA) is a heritable condition characterized by late-onset degeneration of photoreceptor cells in the retina, leading to loss of vision and blindness.
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.
White spotting patterns that occur in many dog breeds do not have a uniform genetic basis, and the genetics are complex. In piebald/parti/random white spotting, the extent of white pattern expression varies, and markings are often asymmetrical.
