So, I'm doing a Project on Forbes' Disease. What is It Exactly?

Basically speaking, Cori-Forbes' Disease is a matebolic disease caused by a deficiency of the enzyme amylo-1,6-glucosidase which is vital in debranching. Muscle, heart and liver cells are typically involved and glycogen has a very hard time breaking down. Thus, there is an excess of glycogen in the liver and muscles. The two clinical variants are 1.an infantile form and 2.a juvenile form.

The biochemical subtypes include: type A, lack immunoreactivity and enzyme activity in both the liver and muscle cells, type B which is only concerned with the liver's immunoreactivity and enzyme activity and type C, a deficiency in transferase activity in both muscle and liver cells, but immunoreactivity and enzyme activities are normal.
