• Collie eye anomaly (CEA)(CEA)

  Augen

  Collie Eye Anomaly is an inherited developmental defect affecting the eye, specifically the retina (the light-sensitive tissue at the back of the eye) and the choroid (the underlying layer of blood vessels). This genetic condition causes these structures to develop abnormally before birth. It is primarily seen in herding breeds and is inherited in an autosomal recessive manner.

• Cerebellar abiotrophy(CA)

  Nervensystem

  Cerebellar abiotrophy is an inherited neurological disorder affecting the brain, specifically the cerebellum, which regulates balance and movement coordination. In affected dogs, the nerve cells in this region prematurely degenerate and die off. This progressive cell loss disrupts the brain's ability to control smooth physical movements.

• Globoid cell leukodystrophy (galactocerebrosidosis)(GCL)

  Nervensystem

  Globoid cell leukodystrophy is an inherited metabolic disorder affecting the nervous system, caused by a deficiency in an essential enzyme. This deficiency leads to the buildup of harmful substances that destroy myelin, which is the protective sheath surrounding nerve fibers in the brain and spinal cord. Without this protective covering, the nerves cannot transmit signals properly, resulting in progressive neurological decline.

• Progressive Retinal Atrophy (prcd-PRA)(PRA)

  Progressive rod-cone degeneration (prcd-PRA) is an inherited eye disease that causes the light-sensitive cells in the retina, which lines the back of the eye, to gradually break down and die. This degeneration affects both eyes and eventually leads to complete blindness. Because the retina cannot process light properly, the dog's brain stops receiving visual information.
