Overview
Brief Summary
Primary Objective:
- To describe the clinical features and their severity at the time of diagnosis and their evolution over time in patients with confirmed chronic visceral and chronic neurovisceral forms of ASMD
- To describe Clinician-Reported Outcomes (ClinROs) and Patient-Reported Outcomes (PROs) at enrollment and their evolution over time; disease severity at the time of diagnosis and its evolution over time
Secondary Objectives:
- To describe abnormal values in laboratory parameters and all values of specific clinical and imaging assessments at the time of diagnosis and their evolution over time
- To study the use and applicability towards validation of a newly developed ASMD disease severity scoring system
- To study the use and applicability towards validation of a newly developed ASMD PRO tool
- To describe ASMD-related disease burden among patients with ASMD, caregivers, and healthcare resource utilization
- To describe the association between patient demographics (eg, age, gender, race, Ashkenazi ancestry) and genotype with selected clinical features in patients with confirmed chronic visceral and chronic neurovisceral forms of ASMD
