This study aims to better understand the genetic factors involved in schizophrenia by collecting saliva samples from people with schizophrenia and individuals without psychiatric disorders across Manitoba. Researchers will use advanced genome sequencing to examine differences in genetic variation and identify genes that may contribute to schizophrenia. By combining genetic information with health and clinical data, this research will help improve our understanding of schizophrenia and support the development of more personalized approaches to treatment and care. People with schizophrenia (cases) will be recruited through participating psychosis clinics in Manitoba, review and sign a consent form, provide a saliva sample for genetic testing, allow researchers to use information already collected through the Manitoba Psychosis Registry and link it with health records. People without schizophrenia or other major psychiatric disorders (screened controls) will be screened to ensure they meet eligibility requirements, review and sign a consent form, complete questionnaires about their health, quality of life, and life experiences, provide a saliva sample for genetic testing, allow researchers to link their genetic information with health records. Objective: To understand how genes contribute to schizophrenia and psychosis by analyzing DNA samples from people with and without these conditions. Endpoints: Collection of DNA samples, identification of genetic differences associated with schizophrenia and psychosis, and understanding how these genetic factors relate to symptoms, health outcomes, and disease risk.
