Longitudinal Assessment of Atypical Tripeptidyl Peptidase 1 Enzyme Deficiency Patients

Neuronal Ceroid-Lipofuscinoses Clinical Trial

Official title: Longitudinal Assessment of Atypical Tripeptidyl Peptidase 1 Enzyme Deficiency (Neuronal Ceroid Lipofuscinosis Type 2) Patients

Status Active, not recruiting

Clinical Trial Summary

The purpose of this study is to gather information on the possible symptoms that patients with atypical neuronal ceroid lipofuscinosis type 2 (also known as aTPP1 or atypical tripeptidyl peptidase deficiency) have and how they change over time.
