New Test Available - Rod-Cone Dysplasia Type 2 (rcd2)
Rod-cone dysplasia type 2 (rcd2) is a type of early-onset retinal degeneration that affects collie breeds and typically leads to blindness. Affected dogs begin to show vision deficits in low light (night blindness) as early as 6 weeks of age and can be completely blind by 6-8 months.
DNA testing for rod-cone dysplasia type 2 can determine the genetic status of dogs. Dogs with one copy of the RCD2 variant are normal but are carriers. Matings between two carrier dogs may, on average, produce 25% of puppies with rod-cone dysplasia type 2.
