Recommendations

 

For students coming from other Universities (Erasmus, etc.), basic knowledge on genetics, biochemistry and cell biology is highly advisable in order to follow the contents of the subject appropriately.

 

 

Competences to be gained during study

 

   -

CB5. Learning skills that are necessary to undertake further study with a high degree of autonomy.

   -

CG2. Capacity for learning and responsibility (capacity for analysis and synthesis, to adopt global perspectives and to apply knowledge in practice, and capacity to take decisions and adapt to new situations).

   -

CB3. Ability to gather and interpret relevant data (usually within the field of study) to inform judgements that include reflection on relevant social, scientific or ethical issues.

   -

CE11. Ability to explain the structure and function of genes and heredity, the basic molecular principles and associated mechanisms of gene expression, and the variability and evolution of genes in specific populations, ability to identify the role of genes in human disease and to classify genetic anomalies, understanding of the principal methods for diagnosing common genetic disorders, and capacity to apply basic techniques for genetic laboratory work.

Learning objectives

 

Referring to knowledge

Describe the genetic and physiopathological bases of monogenic diseases due to occasional mutations, dynamic mutations and large reordering of the genetic material. Genomic, chromosomal and imprinting diseases. Multifactorial diseases. Pathologies of the mitochondrial genome.

As far as possible, the gender perspective will be incorporated into the developent and activities of the subject.

Teaching methods and general organization

 

Lectures and specific seminars on the contents of the programme.

Interactive activities: practical training in the use of databases for genetic diseases.

Discussion of articles and clinical cases, and presentations by students.

 

*The proposed teaching methodology may experience some modifications depending on the restrictions to face-to-face activities enforced by health authorities.

 

 

Official assessment of learning outcomes

 

— The following continuous assessment activities (40% of the final grade) are assessed:

a) a self-assessment test on the contents, mid-semester;
b) a test to assess the ability to track a scientific conference on a specific topic of the course;
c) a questionnaire on the use of the OMIM database on hereditary diseases;
d) a questionnaire and a discussion session on direct-to-consumer testing;
e) seminars on the teaching blocks in the second half of the programme, consisting of the critical analysis (individually or in groups) of a related scientific publication, and an oral presentation (or written assignment).

— Written examination (multiple-choice test) including theory and seminars (60% of the final grade).

*Students’ assessment may experience some modifications depending on the restrictions to face-to-face activities enforced by health authorities.

 

Examination-based assessment
