Functional Capacity in Anderson-Fabry Disease Patients

The goal of this observational study is to observe the relation between excercise parameters - assessed by CPET - and rest/stress hemodynamic parameters - assessed by echocardiogram and CMR - in patients with a genetic diagnosis of Anderson-Fabry Disease. Participants will undergo: * baseline evaluation: clinical evaluation, disease staging with FASTEX and MSSI, KCCQ for quality of life assessment, resting 12-leads ECG, 6MWT, CPET-ESE and contrast-enhanced CMR; * before 36 months from baseline: resting 12-leads ECG, 2D rest and stress echocardiogram, CPET-ESE, contrast-enhanced CMR, disease staging with FASTEX and MSSI and KCCQ for quality of life assessment; * up to 7 years from baseline: clinical follow-up.
