Clinical Trial Summary

This study is a observational study conducted through recruiting X-linked adrenoleukodystrophy (X-ALD) patients, to build a comprehensive evaluation and long-term follow-up platform for X-ALD patients, and to provide a theoretical basis for the treatment and management of X-ALD patients.

Description:

In this study, X-ALD patients will be selected as study participants. Through a longitudinal collection of genetic, imaging and clinical symptoms data of the patients and carriers. The purpose of this study is to build a comprehensive evaluation and long-term follow-up platform for X-ALD patients. Through the long-term follow-up of imaging and clinical symptoms progress and outcome of X-ALD patients, combined with genetic data, we will improve the relationships between genes and phenotypes, and explore the deep insight in the pathophysiological mechanism of X-ALD, to provide a theoretical basis for the treatment and management of X-ALD patients.
