Brief 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.

    5 years

  • Imaging characteristics in Chinese X-ALD patients

    Constructing a Chinese X-ALD patient's head MRI information database by collecting head MRI information from X-ALD patients.

    5 years

  • The disease development in Chinese X-ALD patients

    Record the progress of patients' clinical symptoms from baseline through 5-year follow-up.

    5 years

  • New pathogenic loci of Chinese X-ALD patients in whole genome sequencing/whole exon sequencing

Study Arms (2)

X-ALD

X-linked adrenoleukodystrophy (X-ALD) patients.

Carrier-control (CC)

Carriers of mutation in gene encoding ATP-binding cassette subfamily D member 1 (ABCD1), who have no X-linked adrenoleukodystrophy and are matched with the X-ALD group according to age, sex and education.

Sampling MethodNon-Probability Sample
Study Population

X-linked adrenoleukodystrophy patients, and age,sex and education matched healthy carriers will be recruited from the hospital.

You may qualify if:

  • X-ALD group:
  • Meet the diagnostic criteria of X-ALD and supported by the results of genetic and very long chain fatty acid (VLCFA) test;
  • Age: 6 - 70 years old;
  • Able to communicate normally, and complete the test of scale as instructed (confirmed by the field test of scale);
  • Sign the informed consent.
  • Carrier-control group:
  • Healthy people who have no significant difference in age, sex and education comparing with the X-ALD group, volunteer to participate in this study, could complete the test of scale as instructed, and meet the following criteria:
  • Eligible for asymptomatic carriers in genetic tests (preference of patient's mother and close relatives);
  • Age: 6 - 70 years old, able to complete the test of scale as instructed (confirmed by the field test of scale);
  • No history of psychiatric diseases.

You may not qualify if:

  • Other hereditary diseases;
  • Other severe central nervous diseases;
  • History of surgery of brain or eye;
  • Psychiatric and psychological diseases, such as anxiety and depression;
  • Metal foreign body or prosthesis in the human body (such as pacemaker and insulin pump), claustrophobia, and other MRI contraindications;
  • History of surgery associated with gastrointestinal tract;
  • No informed consent;
  • Unable to tolerate MRI or eye related tests.
