SNP Clinical Trial Gene

A Prospective and Retrospective Cohort Study to Refine and Expand the Knowledge on Patients With Chronic Forms of Acid Sphingomyelinase Deficiency (ASMD)

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
