Final answer:
The AKT1 gene may be related to the development of psychosis and schizophrenia in patients, particularly in interaction with environmental factors.
Step-by-step explanation:
The AKT1 gene has been studied in relation to psychosis and schizophrenia. Research suggests that the AKT1 gene may play a role in the development of these conditions, particularly in interaction with environmental factors. In a study of adoptees, it was found that those with a high genetic risk for schizophrenia and raised in disturbed home environments were more likely to develop the condition than other groups. This indicates that both genetic vulnerability and environmental stress are necessary for schizophrenia to develop.
