Report for Mutation L304P
Developed by Shray Alag, 2020.
SNP Clinical Trial Gene
There is one clinical trial.
Clinical Trials
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
Exclusion criteria:
Patients suspected or diagnosed with infantile onset ASMD (ie, NPD A, with progressive
developmental delay, or presence of any combination of R498L, L304P, and P333fs*52
genotypes, if available),
- Patients having received or receiving an investigational drug,
- Patients receiving any ASMD specific ERT,
- Patients with poor general condition that would not be able to undergo study
assessments as per investigator's clinical judgment. --- R498L --- --- L304P ---
