Achromatopsia, Day blindness, Hemeralopia, Rod monochromacy, CD1
Cone degeneration (also called Achromatopsia) is a disease characterized by loss of cone photoreceptor function, resulting in daytime blindness, complete color blindness and reduced central visual acuity. The cause of this disease is a deletion involving several genes, including the key gene CNGB3.
The disease mainly affects breeds of Arctic lineage such as the Siberian Husky or the Alaskan Malamute.
Inheritance is autosomal recessive.
