-
Genetic-guided psychotropic medication choices for adults in Manitoba
This project will test whether using a patient's genetics to guide psychotropic medication choices helps adults in Manitoba who are starting or changing psychiatric medicines.
-
Evaluating drug reactions in patients taking multiple medications using genome sequencing
This study is testing if using genetic information can help doctors better manage medications and reduce bad reactions in patients taking five or more drugs.
-
Registry for understanding how genes affect medication responses
This study is trying to see how your genes affect how you respond to medications, so doctors can better choose the right treatments for you, especially if you're taking several drugs or have had bad reactions to them.
-
Using genetic testing to improve medication safety for children
This study is testing whether genetic testing can help doctors choose safer medications for children to reduce the risk of bad reactions.
-
Identifying genetic factors in drug reactions in children and adults
This study is trying to find out if genetic differences in children and adults can help explain why some people have bad reactions to medications while others do not.
