Glycogen Storage Disease Type IV MeSH Descriptor Data 2025
do not confuse with ANDERSEN SYNDROME, a potassium-sensitive familial periodic paralysis
Scope Note
An autosomal recessive metabolic disorder due to a deficiency in expression of glycogen branching enzyme 1 (alpha-1,4-glucan-6-alpha-glucosyltransferase), resulting in an accumulation of abnormal GLYCOGEN with long outer branches. Clinical features are MUSCLE HYPOTONIA and CIRRHOSIS. Death from liver disease usually occurs before age 2.
