In the Giant Schnauzer, a specific form of progressive retinal atrophy (PRA) is associated with a mutation in the NECAP1 gene. The first symptoms typically appear around the age of 4. This disease is characterized by progressive retinal degeneration leading to blindness.
This test is also mandatory for Dachshunds and Pomeranians as part of the Flemish government's breeding program (see the official program).
