Informations générales

Achromatopsia (sometimes referred to as Cone Degeneration or Hemeralopia) is an eye disorder that can cause day blindness, sensitivity to light and a loss of colour vision. This particular form of the disorder is known as Achromatopsia-3, and is caused by a recessive mutation to the gene CNGB3. The variant analysed in this test occurs in the German Shorthaired Pointer. A related variant has been found in the Alaskan Malamute, Siberian Husky and Australian Shepherd.

Caractéristiques cliniques

Affected dogs generally begin displaying symptoms of day blindness and photophobia (sensitivity to bright light) between the ages of 8 and 12 weeks. Only the dog’s bright-light vision is affected; vision remains normal in dim light.
