Progressive retinal atrophy (Type B1-PRA, HIVEP3)
Progressive retinal atrophy (Type B1-PRA, HIVEP3)
General description
According to the latest scientific research, a mutation in the HIVEP3 gene is responsible for the early form of type B PRA in miniature schnauzers. The previously offered type B 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.

Detailed description
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.\nAccording to the latest scientific research, a mutation in the HIVEP3 gene is responsible for the early form of type B PRA in miniature schnauzers. The previously offered type B PRA test via Optigen (now called GeneSeek) has examined a genetic variant in the PPT1 gene that showed variations in genotype and phenotype. \nThe newly discovered HIVEP3 variant shows a better correlation, which is why we recommend the newer test according to Kaukonen et. al. \n
