Learning Objectives

The course is focused on the acquisition of the fundamental principles of medical genetics, genetic diseases, and personalized genomic medicine.

The course will provide students with the knowledge of the mechanisms of genetics in medicine. The course aims to share knowledge on genetic diseases, their mechanisms and therapeutic perspectives. Particular attention is paid to the principles of personalized genomic medicine and to the applicative possibilities of pharmacogenomics in clinical practice.

Program

Learning Achievements (Dublin Descriptors)

D1 - Knowledge and ability to understand. The student will show mastery in basic knowledge of molecular genetics, cytogenetics, familial pedigrees, patterns of disease transmission, pharmacogenomics and personalized medicine.

D2 - Ability to apply knowledge and understanding. The student will demonstrate understanding of concepts and theories provided by the course; students will provide examples of genetic diseases (biological, clinical, hereditary, and analytical skills); they will be able to analyze familial pedigrees, identifying patterns of transmission, recurrence risks, available tests.
