General information
Imerslund-Gräsbeck Syndrome (IGS), also known as Selective Intestinal Cobalamin Malabsorption (ICM), is a disorder in which the intestines fail to absorb enough Vitamin B12. This variant, found in the Border Collie, is caused by a recessive mutation to the gene CUBN. Similar variants also occur in the Beagle and Komondor.
Clinical features
Affected dogs start presenting within the first few weeks to months life with poor apetite and poor weight gain. Other symptoms may include difficulty swallowing, painful sores on the tongue, chronic diarrhea, heartbeat irregularities, anemia, and chronic fatigue.
