Glycogen Storage Disease Type III

Also known as Cori disease or debrancher enzyme deficiency.

Children with GSD III are often first diagnosed because they have been noticed to have a swollen abdomen due to a very large liver. Some children have problems with low blood sugars on fasting but this is not as common as in GSD I.

Growth may be delayed during childhood but the majority attain a normal final adult height. Although some older individuals develop problems with muscle weakness (which may also affect the heart), the outcome for most is good with the liver returning to a normal size with age.
