Evaluation of Phenotypic Variability in Fabry Disease
2020年12月1日 更新者:Farrah Rajabi、Boston Children's Hospital
Cerebrovascular events, such as stroke, are a devastating complication of Fabry disease that results in part from storage of complex lipids in both large and small vessels.
Understanding how the genotype influences the phenotype or clinical presentation can help us understand which patients are at risk for the complications of Fabry disease.
This study aims to follow the natural history of this disease will help us understand and predict long-term outcomes for patients.

详细说明
This longitudinal study will be conducted at Boston Children's Hospital (BCH).
Subjects recruited for the study will have routine clinical care assessment with a complete physical and neurological exam and biochemical monitoring with venipuncture.
In addition as part of the study, subjects will be given questionnaires to assess details of medical and psychosocial history, will complete self-reported measures of neuropsychological evaluation, pain scores, quality of life, executive functioning and cognitive functioning.
All patients assessments will be repeated every 2 years.
