Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

We are going to investigate the association of multiple genetic polymorphisms with the metabolic side effects in patients with schizophrenia taking clozapine.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The use of antipsychotics, especially clozapine and olanzapine is associated with metabolic side effects, which put patients with schizophrenia at risk for cardiovascular morbidity or diabetes.

The prevalence of the metabolic syndrome was 53.8% of patients who taking clozapine. The high interindividual variability in antipsychotic-induced metabolic abnormalities suggests that genetic makeup is a possible determinant.

The genotypes of the multiple gene such as HTR2C, LEP, adrenergic receptor,PPAR,GNB3 are suggested to have associations with the metabolic side effects (weight,glucose,lipid,BP,metabolic syndrome) in patients using antipsychotics.

We are going to investigate whether those multiple genetic polymorphisms are associated with the metabolic side effects in patients taking clozapine.
