Progressive retinal atrophy (Type B1-PRA, HIVEP3)

LABOKLIN Service ID: 8546

Progressive retinal atrophy (PRA) is a progressive disease of the retina. The photoreceptors of the eye are destroyed over time. This leads to increasing night blindness and loss of vision adaptation.
According to the latest scientific research, a mutation in the HIVEP3 gene is responsible for the early form of type B1-PRA in miniature schnauzers. The previously offered type B1-PRA test via Optigen (now called GeneSeek) has examined a genetic variant in the PPT1 gene that showed variations in genotype and phenotype.
The newly discovered HIVEP3 variant shows a better correlation, which is why we recommend the newer test according to Kaukonen et. al.
