Evaluation of the Gastrointestinal Manifestation of Fabry's Disease

Patients will undergo a SmartPill test to gain additional understanding of Fabry disease manifestation via motility abnormalities in order to improve symptom targeted therapy. An additional Endoscopic mucosal resection may be performed on further qualifying patients. Tissue analysis from this biopsy will include evaluation of abnormalities of cellular structure and morphology with correlation with gastrointestinal complaints for each patient and comparison against age matched non-Fabry patient tissue. The hypothesis is that patients with fabry disease will have abnormal motility which will correlate with the patients symptoms and quality of life as noted on the questionnaires.
