Phosphorylase b kinase deficiency glycogenosis with cirrhosis of the liver

J Pediatr. 1995 Oct;127(4):602-5. doi: 10.1016/s0022-3476(95)70123-0.


We describe an Arab girl with complete absence of phosphorylase b kinase activity in the liver, symptomatic hypoglycemia, and persistently elevated serum aminotransferase values whose symptoms did not lessen with age; sequential liver biopsies showed progression to cirrhosis. Cirrhosis could not be ascribed to any other known cause. We conclude that type IX glycogenosis is not always associated with a benign outcome.
