Learning objectives
The goal of the course is to describe the genetic mechanisms underlying the transmission of Mendelian characters to identify the inheritance of diseases in humans evaluating the reproductive risk through the study of family trees. The course is also aimed at providing the future medical doctor with the tools to understand the molecular mechanisms at the basis of the main genetic disorders involving genes, and chromosomes, and the use of novel diagnostic tests.
These skills will allow the patient to be directed to more specific diagnostic and clinical investigations, to assess the inheritance risk of pathological trait, and / or identify the liability to a specific disorder, reducing environmental risk through appropriate lifestyles
Expected learning outcomes
At the end of the course the student should be able to draw a family tree, distinguishing the different types of inheritance, indicate the possible genetic and environmental factors in multifactorial diseases, classify mutations involving genes and chromosomes, describe the most common genetic disorders, and be able to calculate the frequency of a disease gene in a population, evaluating the presence of healthy carriers. The student must also have understood, the main strategies used in cytogenetic-molecular diagnosis, applied in pre- and post-natal genetic counseling
Single course

This course cannot be attended as a single course. Please check our list of single courses to find the ones available for enrolment.

Course syllabus and organization

Surname A-L

Prerequisites for admission
Although some concepts will be reviewed, the topics covered during the Open Semester are assumed to be already acquired with particular reference for molecular biology to the structure of macromolecules (DNA, RNA, proteins), transcription and replication in prokaryotes, the structure of transcription factors, and the regulatory mechanisms of the lactose operon. For the Genetics module, students are expected to have already acquired Mendel's laws and their application to the inheritance of normal and pathological traits in humans through the construction of pedigrees, as well as gene interactions and the concepts of epistasis, genetic complementation, expressivity, and penetrance. Students must also be familiar with the organization of the human genome and be able to describe its variability through polymorphisms.
For the Medical Genetics section, the topics covered during the open semester and the first part of the course (Molecular Biology/Applied Biology) are assumed to have been already acquired. The student is expected to be familiar with the organization of the human genome and its variability, as well as basic concepts of population genetics and epigenetics.
Assessment methods and Criteria
For both teaching tracks, the exam is divided into two modules (Molecular Biology, comprising 3 credits of Molecular Biology and 1 credit of Applied Biology; Genetics, comprising 2 credits of Medical Genetics), which are assessed independently.
For Molecular Biology, the first three exam sessions will be held in written form (duration: 1 hour and 15 minutes) and will include multiple-choice questions and open-ended questions aimed at assessing students' knowledge and understanding of the entire course programme. Subsequent exam sessions will be held orally and will consist of an interview with the course lecturers, during which students' knowledge and understanding of the topics covered in class or included in the preparation for the open semester, as well as their command of subject-specific terminology, will be assessed.
For Genetics, the first exam session will be held in written form (duration: 1 hour) and will include multiple-choice questions covering the entire module programme. Subsequent exam sessions will be held orally and will consist of an interview with the course lecturers.
The results of the written exams will be published anonymously on the dedicated University portal. The final mark, expressed out of thirty, will be the weighted average of the mark obtained in the Molecular Biology module (4 credits, corresponding to 2/3 of the final mark) and the mark obtained in Genetics (2 credits, corresponding to 1/3 of the final mark), and may be recorded only after both modules have been passed.
Students are required to use a Molecular Biology textbook and will have access to the lecture slides.

Teaching methods
The module will consist of frontal lectures with slide shows in Power Point. In all teaching moments, students will be exhorted to find experimental strategies useful for solving small scientific problems or to consider the possible biomedical, diagnostic and clinical applications deduced from the acquired knowledge.
The teaching material consisting of presentations in PDF format will be made available at the end of the lesson on the Ariel platform.
Attendance of teaching is mandatory.
Regarding Innovative Teaching activities, clinical cases and examples of possible genetic test outcomes will be provided, which students will be asked to interpret based on the knowledge acquired during lectures and through the use of online tools. The activities are to be carried out asynchronously, during or at the end of the course, by completing Tests or submitting assignments on the Ariel platform.
