MEDICAL GENETICS THIRD YEAR
Academic Year 2022/2023 - Teacher: CORRADO ROMANOExpected Learning Outcomes
At the
end of the Course the students should:
- Describe the different genetic variations of the human genome, and explain their role in health and disease.
- Make the analysis of pedigrees and understand the principles of inheritance, for the calculation of genetic risk in a range of genetic diseases and modes of inheritance.
- Include the items of population genetics for the calculation of genetic risk based on allelic frequency within the population.
- Know nonmendelian mechanisms, such as decreased penetrance and variable expressivity, uniparental disomy, mosaicism, imprinting and dynamic mutations.
- Understand the molecular bases of developmental genetics and cancer.
- Know the principles of genetic counseling and pharmacogenetics.
Course Structure
If teaching will be shifted to mixed or remote mode, the needed amendments will be pursued, for the correct accomplishment of the program shown in the syllabus.
Required Prerequisites

Learning Assessment
Learning Assessment Procedures
Oral
test/examination
The test
will be a conversation where two-four questions will be asked by the teacher on
at least two topics of the program. The test will acknowledge: i) the rate
of knowledge of medical genetics; ii) the ability of problem solving
within the field of Medical Genetics; iii) the clarity of speech; iv) the
appropriate scientific medical wording.
The
final marks will be given according to the following criteria:
29-30 cum laude: the student has a thorough knowledge of medical genetics, can
quickly and correctly understand and critically analyze the provided
scenarios, solving on his/her own complex issues; has brilliant
communication skills, and masters scientific medical wording.
26-28: the student has a good knowledge of medical genetics, can understand and
critically and straighforwardly analyze the provided scenarios, solving
almost on his/her own complex issues, and shows clearly the topics with an
appropriate scientific medical wording.
22-25: the student has a discrete knowledge of medical genetics, but restricted
to the main topics; can critically, but not ever straightforwardly,
understand and analyze the provided scenarios.
18-21: the student has the minimal knowledge of medical genetics, has a modest
ability of critically understanding and analyzing the provided scenarios,
and shows with a sufficient clarity the topics, but a poorly developed
scientific medical wording.
Failed test/examination: the student does not show the minimal knowledge of the
main topics of the Course. The ability of using the scientific medical
wording is very poor or absent, and cannot apply on his/her own the
acquired knowledge.
