Every FMK condition
299 diseases, deficiencies, toxicities and drug mechanisms harvested from every FMK deck — the ones sprinkled through a single bullet as much as the ones with their own slide. Pick what you're given and what you have to name, or let it cycle; distractors come from the same category so you have to discriminate (hypoketotic vs. ketotic hypoglycemia, which GSD, which urea-cycle enzyme…). Every answer shows the whole card with the lecture and slide.
Glycogen · FMK 03.6
Andersen disease (GSD Type IV) Autosomal recessive
Defect / target: Branching enzyme (4:6 transferase)
Mechanism: Glycogen cannot be branched, producing abnormal poorly soluble amylopectin-like glycogen that damages the liver.
↑ Accumulates: abnormal unbranched glycogen (polyglucosan) in liver and muscle
Presentation: cirrhosis, progressive hepatic failure, death in early childhood
