Conoscenze e abilità da conseguire

At the end of the course the student has knowledge of the main experimental designs and tools applied in genetics and genomics and approaches for genetic and genomic data analysis, with an emphasis on vertebrate genomes including genetic mapping, QTL, eQTL analysis, and next generation sequencing. In particular the student is able to: understand the structure of genetic variability and its phenotypic effects, browse vertebrate genomes, apply methods to identify disease genes and QTL, use software for genomic data analysis, correctly interpret results and plan genetic studies in a proper way.

Contenuti

Prerequisites:

The knowledge of genetics and molecular biology are important prerequisites to follow the course. Who might have gaps in these fields is strongly encouraged to contact the professor at the beginning of the course. Together, the student and the professor will prepare ad hoc plans to fill any gaps.

Program of the 16 lectures:

1) Introduction to the course - Foundational concepts in genetics (including population and quantitative genetics) and genomics. Basic technologies and approaches in genomics (Fontanesi)

2) Next generation sequencing (NGS) technologies I (Fontanesi)

3) Next generation sequencing (NGS) technologies II (Fontanesi)

4) How to sequence a complex genome – genome assembly (Fontanesi)

5) Genome databases, annotation and features of a complex genome (Fontanesi)

6) Genome variability: applications and analysis of case studies (Fontanesi)

7) Next generation sequencing data analysis – case study I (Bovo)

8) Next generation sequencing data analysis – case study II (Bovo)

9) Developing high throughput genotyping tools – use of these tools (Fontanesi)

10) Elements of population genomics (linkage disequilibrium, linkage analysis, ROH, etc.) (Fontanesi)

11) Genome wide association studies - GWAS (Fontanesi)

12) Use of software for population genomic analysis and GWAS (Bovo)

13) Use of software for population genomic analysis and GWAS (Bovo)

14) Planning a genomic project I (Fontanesi)

15) Planning a genomic project II (Fontanesi)

16) Examples of genomic projects (Fontanesi)

5) Scientific articles, references and software are provided to the students during the course.

6) Lecture slides are given to the students.

7) Some good projects of the previous years will be shared with the students.

8) Auto-evaluation test will be given to the students.

Students are advised to take notes from the lectures which should be integrated with indicated books/chapters. Tools and software will be provided during the course.

Metodi didattici

Lectures. Exercises during the course for specific aspects. Analysis of scientific papers during the lectures. Each student plans a genomic project.

Guideline on how to plan the genomic project:

1) A virtual budget will be assigned (randomly)

2) The student, based on the program of the course, will develop her/his idea of a project that should answer a question related to the current state of the art of a defined field of applied genomics – selected by the student

3) The considered species should have a complex genome (therefore no prokaryotes or viruses are usually accepted)

4) The student should use the virtual money assigned by virtual spending the budget on genomic analyses and on the planning of the project design and implementation

5) The assigned budget should cover: cost of sampling biological materials/specimens in the field or in other contexts, DNA extraction, NGS and/or high throghput genotyping in outsourcing, computational costs could be eventually included, etc. (no instruments should be bought)

6) The aim of the project should be balanced according to the available budget

7) The project expected results should be reliable according to the study design

8) A budget balance should be provided to demonstrate that all virtually available money is spent (virtually)

9) Examples will be discussed during the lectures (based on case studies) Plans of genomic projects will be detailed discussed in the last three lectures


Modalità di verifica dell'apprendimento

The final exam valuates the students according to the following objectives:

1) knowledge of the foundational concepts in genetics and genomics;

2) knowledge of advanced technologies for genome analysis;

3) knowledge of advanced applications of genomic tools to answer biological questions in vertebrates;

4) capacity planning of genomic experiments.

The final exam has two levels:

1) Preparation of a genomic project: a text should be written including an appropriate introduction to the problem/question that the experiment or project would like to analyse or answer, aim of the project, a section with materials and methods, expected results and impact. The project should be submitted to the professor one week before the interview.

2) Interview based on the project submitted and other two questions according to the main objective of the course. Only students that are positively evaluated at the first level are admitted at the second level.

The final score will be based on the performance of the students at the two levels.

Strumenti a supporto della didattica

Scientific articles, references and software are provided to the students during the course. Lecture slides are given to the students at the end of the course.
