Primary Outcome Measures

Name	Time	Method
Bipspecimen collection from subjects that are diagnosed with Glycogen Storage Disease Type Ib (GSD1b, von Gierke disease); Subjects that are the biological parent of subjects diagnosed with Glycogen Storage Disease Type Ib (GSD1b, von Gierke disease)	1 Year	Bipspecimen collection from subjects or their parental guardians that are diagnosed with Glycogen Storage Disease Type Ib(GSD1b, von Gierke disease) for the purpose to analyze the biospecimens to support the investigation of potential therapies that address the genetic basis of this disease. The primary outcome measure is the collection of biospecimens for quantitative analysis using PBMC processes to report cell viability of at least 5M cells per vial.
