Study of the Role of G72 in Amyotrophic Lateral Sclerosis: Biomarker Discovery and Mechanism Investigation
An observational study of Amyotrophic Lateral Sclerosis and Alzheimer Disease, run by China Medical University Hospital.
Trial summary
G72 gene is located on the common linkage locus in bipolar disorder and schizophrenia, and it encodes D-amino acid oxidase activator (DAOA). There are evidences that elucidated G72 and D-amino acid oxidase(DAO) together playing a critical role in the pathophysiology of schizophrenia. Read more about this study

About this study
G72 gene is located on the common linkage locus in bipolar disorder and schizophrenia, and it encodes D-amino acid oxidase activator (DAOA). There are evidences that elucidated G72 and D-amino acid oxidase(DAO) together playing a critical role in the pathophysiology of schizophrenia. Recently, reports discovered missense mutations in the DAO (R199W DAO and R38H DAO) are associated with familial amyotrophic lateral sclerosis (FALS), and our preliminary data showed that the level of G72 autoantibody decreases in patients with ALS compared with normal control. Thus, we want to find out whether G72 plays a role in ALS and neurodegenerative diseases including Alzheimer disease and Parkinson's disease. First, we detect G72 protein and its autoantibody in sera of neurodegenerative diseases patients using ELISA and Western blotting, and the data are compared with normal control. We hypothesize the levels of G72 protein and its autoantibody in neurodegenerative diseases are less than those in normal control. Then, we extract genomic DNA of neurodegenerative diseases patients, and use polymerase chain reaction(PCR) to detect single nucleotide polymorphism (SNP) of G72. We aim to detect G72 missense SNP variants presented in ALS, AD and PD.

Questions about this trial
What is this clinical trial studying?
An observational study of Amyotrophic Lateral Sclerosis and Alzheimer Disease, run by China Medical University Hospital.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 22 Jun 2011. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jun 2011; AzTrials last refreshed its copy on 8 Nov 2026.
