Summary

This study gathers medical information from 200 people with GBE deficiency, which includes two rare conditions: Glycogen Storage Disease Type IV (GSD IV) and Adult Polyglucosan Body Disease (APBD). The goal is to learn how the disease progresses over time by reviewing records from routine clinic visits. No new treatments are tested—this is purely an observation study to better understand the disease.
