In Shetland Sheepdogs (also known as Shelties) a form of PRA which is called Bardet-Biedl Syndrome Type 2 occurs. This variant is caused by a recessive mutation to the gene BBS2 and can now be tested with test number H866 or as part of the CombiBreed package Shetland Sheepdog (H586).<\/p>\n
Affected Shelties present in adulthood (approximately between the ages of 8 and 10 years) with a progressive decline in vision, starting with night vision and followed by daylight vision. Additionally, the disorder can cause unusual physical features such as an upturned nose, a wavy coat and dental abnormalities such as loose teeth.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
