A medical information processing apparatus according to the present embodiment includes a processing circuitry. The processing circuitry is configured to acquire gene therapy information in which a candidate agent that is a therapeutic agent for a gene mutation related to a disease of a patient, an effect of the candidate agent, and ancillary information on the candidate agent are associated with one another. The processing circuitry is configured to determine a priority order of the candidate agent based on the gene therapy information and patient information on the patient. The processing circuitry is configured to present the priority order in association with information representing a relationship between genes.
