Disease
A different form of blindness called rod cone dysplasia, or Rdy has also been identified in Abyssinian and Somali cats. The mutation is a single base pair deletion in a different gene, CRX, which also results in a defective protein that is critical for eye development. Cats carrying one copy of this mutation have retarded development and degeneration of photoreceptor cells, which leads to early-onset blindness by 7 weeks of age.
