Association of the DISC1 and NRG1 genetic polymorphisms with schizophrenia in a Chinese population.

Polymorphisms in Disrupted-in-Schizophrenia 1 (DISC1) and Neuregulin 1 (NRG1) might be associated with schizophrenia; however, the conclusions of relevant studies were inconsistent across different ethnic populations. This population-based case-control study was carried out to determine whether polymorphisms in these two genes could be associated with schizophrenia in the Chinese population. A case-control study of 248 schizophrenia patients and 236 controls was performed with the Sequenom MassARRAY platform.
