Knowledge of the mode of inheritance of genetic disorders in humans and the underlying molecular mechanisms. Comprehension of experimental approaches for the detection of genetic factors associated to human diseases. Basic concepts on population genetics.
The course aims at deepening into the many pattern of inheritance of genetic disorders and the underlying molecular causes. In addition, we will present the variety of experimental approaches to the study of human genetic disorders, including cytogenetic techniques and novel sequencing technologies. We will also deal with the management of bioinformatic data related to sequencing analysis. We will hence approach basic concepts of population genetics and factors influencing the distribution of variants. Finally, the course will provide information about inheritance of common polygenic and multifactorial disorders and presents methods to identify susceptibility factors.
The course is organized in frontal lessons held in English. The topics included in the syllabus will be explained by the professor through PowerPoint presentation, also using examples from scientific papers. Students will be stimulated to ask questions and formulate answers using interactive modalities.

II semester, March 2022
The exam is carried out as oral test in English or in Italian, as preferred by the student. The final vote is expressed out of 30.
The oral exam, in English or Italian, will allow to test students on most of the content of the course, by assessing their knowledge on human genetics, as well as the acquired ability to connect different topics and to eventually solve genetic problems.
Proficiency in English language, if opted by the student, will not be evaluated, but it must be sufficient to show the student’s knowledge of the subjects, with an adequate level of expertise.
