Study of Glycogen Storage Disease Expression in Carriers

Completed

• Conditions: Glycogen Storage Disease

• Registration Number: NCT02057731
• Lead Sponsor: University of Florida

Brief Summary

The purpose of the study is to determine whether carrier status for any type of glycogen storage disease (GSD) predisposes the carrier to GSD markers, like high cholesterol, by testing blood, urine, and saliva samples.

Detailed Description

Subjects will be asked to contribute about a teaspoon of blood, 1 oz of urine, and 2 tablespoons of saliva samples in the morning before they have had anything to eat. The blood and urine samples will be tested for the markers of GSD, while the saliva sample will be used for genetic testing. Subjects' height and weight will also be measured.

Subjects will also be asked to fill out a questionnaire about symptoms common to full GSD expression that they may have experienced, as well as if they are currently on any medication to control their cholesterol.
