Schizophrenia (cases)
The schizophrenia case group will consist of Manitoba residents aged 18 years and older who have a clinical diagnosis of schizophrenia based on standard DSM-5 criteria and who are already enrolled in the Manitoba Psychosis Registry (MPR).
Participants will be recruited through psychosis-focused clinical programs in Manitoba, including the Early Psychosis Prevention and Intervention Service (EPPIS), Schizophrenia Treatment and Education Program (STEP), Program of Assertive Community Treatment (PACT), and Assertive Community Treatment/Flexible Assertive Community Treatment (ACT/FACT) teams.
Cases will provide saliva samples for DNA extraction and whole genome sequencing, and genetic data will be linked with clinical information, questionnaire data, and provincial health administrative data to investigate the genetic basis of schizophrenia and related health outcomes.
|
|
Control (screened)
The screened control group will consist of Manitoba residents aged 40 years and older who have no known history of psychiatric disorders.
Potential controls will be identified through the Manitoba Population Research Data Repository and recruited by invitation.
Individuals will be excluded if they have had contact with a psychiatric specialist or have a history of antidepressant, lithium, mood stabilizer, or antipsychotic medication use.
Participants will provide saliva samples for DNA extraction and whole genome sequencing, and their genetic data will be linked with provincial health administrative data.
This group will serve as a comparison population for investigating genetic differences associated with schizophrenia.
|
|
Control (unscreened)
An unscreened control group of approximately 2,500 individuals from Manitoba and Saskatchewan will be included through the PrairieGen project.
These participants were sequenced using the same whole genome sequencing technologies as the study participants and represent the general Prairie population.
While no psychiatric screening or health administrative data linkage will be available for this group, they will provide a population-based genetic reference to improve statistical power and enhance the generalizability of genetic findings.
