Ten Year Follow-up in FSHD: the FOCUS 3 Study

This study aims to assess longitudinal data in 170 adult and 30 pediatric genetically and clinically well-defined facioscapulohumeral dystrophy (FSHD) patients. FSHD is a chronic progressive disorder associated with major disability due to loss of function and independence. The clinical variability of FSHD is partially explained by currently known (epi)genetic factors. Identifying the variables that influence the clinical variability is essential for developing targeted therapies. Furthermore, it is crucial to assess the natural course, determine sensitive outcome measures and biomarkers to prepare for future trials. Objective This is a longitudinal study on 200 Dutch FSHD patients with a follow-up of ten years. We will hereby assess the natural disease course; determine the sensitivity to change of clinical outcome measures and muscle imaging; validate newly developed outcome measures; and help identify biomarkers and modulators of disease severity. Study population: Genetically proven FSHD patients: All 162 patients that participated in the FSHD-FOCUS study, together with all 18 pediatric patients that participated in the iFocus study , and additional 65 newly included patients. Main study parameters/endpoints: Natural history will be assessed by 'traditional' clinical outcome measures: Motor Function Measure D1, Ricci-score, MRC scores and FSHD clinical score for adults. Additionally in children shoulder dysfunction performance of upper limb and Facial weakness score will…
