Intractable fever and cortical neuronal glycogen storage in glycogenosis type 2.
Glycogenosis type 2 is an autosomal recessive glycogen storage disorder caused by deficiency of lysosomal acid alpha-glucosidase. Different phenotypes are recognized. The authors describe two children affected by the late infantile form; both presented terminal hyperthermia not caused by infections. Autopsy performed in one case showed diffuse glycogen storage in the CNS neurons. In light of current interest in enzyme replacement therapy, this finding casts some doubt on how effective enzyme replacement therapy will be unless it can be targeted directly into the CNS.
