A Gene for Blindness in Dogs

Scientists discovered a genetic mutation in dachshunds that's related to cone-rod dystrophies, reports the BBC. In work published in Genome Research, doctors at the Norwegian School of Veterinary Science isolated a gene called NPHP4, a portion of which had been deleted in affected dachshunds. The mutation only affects the eyes, suggesting that it might be a drug candidate for humans with the disease.
