Genetic Test
The CRX (Cone-Rod Homeobox) gene encodes the cone-rod homeobox protein, which plays an essential role in regulating the expression of various proteins involved in photoreception. This genetic test targets one specific gene variant associated with rod-cone dysplasia.
Disease Description
Rod-cone dysplasia is a congenital retinal disease characterized by abnormalities affecting rod and cone cells—the photoreceptive cells responsible for sensing light in the retina. Affected cats typically show initial clinical signs between approximately 1.5 to 2 years of age, as the functions of rod and cone cells deteriorate. Over time, the condition leads to progressive vision loss, culminating in complete blindness by around 3 to 4 years of age.
