Rare Glycogen Storage Diseases Natural History Study

Summary

The purpose of this study is to collect and study key medical data about several ultra-rare GSDs (Glycogen Storage Diseases) including, but not limited to, GSD types 0a, 0b, VII, X, XII, XIII, XV, PRKAG2 syndrome and Danon disease.

Detailed Description

The immediate goal of this research is to create a natural history database to collect information from individuals who have a rare GSD. A repository of clinical, laboratory, and biochemical information on individuals with a rare GSD will allow a more definitive description of the different subtypes to be developed, which will permit development of treatment strategies in the future. Duke will be the only site where this study takes place. However, since these are rare disorders, participants who receive care at other institutions will be included. The investigators will collect retrospective data from patient charts on diagnosed individuals, as far back as necessary to capture the clinical course of their disorder. Prospective data collected from patient charts after enrollment will be captured as well. Participant's medical records will be continually reviewed for the duration of the study. Data will be collected from medical records and will only pertain to clinically relevant information, including, but not limited to: demographic and diagnostic information, tissue biopsy results, medical and family history, review of systems, imaging studies, results of liver, muscle, and nerve function testing, and urine and blood laboratory results.
