Compared to normal glycogen the amount of what type of bond is decreased in lafora bodies

Compared to normal glycogen, the type of bond that is decreased in Lafora bodies is Alpha 1-6 Glycosidic Bond.
Lafora normally functions as a phosphatase in normal people. If there is a mutation in the Lafora gene, there is an accumulation of covalently bound phosphates. Lafora bodes are glycogen polymers. The linkage of alpha 1-6 glycosidic bonds. 

The correct answer is the glycosilic bond. Lafora disease is a neurodegenerative disease characterized by the presence of Lafora bodies in the cytosol. This disease causes impairment in the development of cerebral cortical neurons and it is a glycogen metabolism disorder. Lafora bodies are are aggregates of polyglucosans or abnormally shaped glycogen molecules ( abnormal chain lengths with higher phosphate levels).
