DNA test - IGS (Imerslun-Gräsbeck syndrome/Cobalamin malabsorption)

Details about the disease

This clinical condition occurs because vitamin B12 is not absorbed properly in the small intestine. Vitamin B12 is needed for normal cell growth and in conjunction with iron and folic acid; it ensures that the nervous system functions properly.

Clinical signs

First signs usually appear early in a dog’s life and include a loss of appetite and lethargy (lack of energy). Puppies with this disorder will fail to grow normally. Anaemia (reduced number of red blood cells) is also a result of this condition and this will cause affected puppies to become weak with a decreased ability to exercise.

How is it inherited?

The disease is described as an autosomal-recessive condition. This means that a dog must inherit two copies of an abnormal gene (one from its mother and one from its father) before its health is affected. A dog that inherits only one copy of the abnormal gene (from its mother or its father) will have no signs of the disease, but will be a carrier and may pass the gene on to any offspring.
