MBI-3013 Human molecular genetics: medical and forensic genetics - 10 ECTS
The course is an elective course for students accepted to the Master´s program in Biomedicine.
The course can be taken as a singular course by students with a Bachelor´s degree in Biomedicine or similar (180 ECTS).
Recommended prerequisites: Basic knowledge at University Bachelor level in general genetics and cell- and molecular biology.
Application deadline for nordic applicants is 1st of December. Applicationcode: 9371
Admission requirements: see admission requirements for the Masterprogram in biomedicine
The first part of this course will focus on basic topics in human genetics, such as the structure and function of chromosomes, the organization and evolution of the human genome, DNA sequence variation and the characteristics and regulation of protein coding and non-coding genes.
The next part will cover different topics in medical genetics, such as Mendelian inheritance, population genetics, mutations, and epigenetics in relation to diseases. Furthermore, lectures will be given on theory and methods for molecular genetic diagnostics as well as classic- and molecular cytogenetics.
The last part of the course will give a short general introduction to the discipline of forensic medicine, before focusing on forensic genetics and the analysis of biological traces in criminal cases. Lectures will cover the principles for detecting different body fluids, DNA-profiling using STR-markers, interpretation of the results and statistical calculations for evaluating the strength of DNA evidence. The analyses of alternative markers like SNPs and markers on Y-chromosomes and mitochondrial DNA will also be discussed.
The course will shortly cover some ethical and legal aspects related to both medical and forensic analyses and also give an introduction to new molecular methods in these disciplines.
During a laboratory exercise, the students will analyze evidence from a simulated criminal case using methods that are generally used in molecular genetics.
After the course the student should be able to:
- Explain the structure and organization of human chromosomes and the organization of the human genome
- Explain some basic theories for evolution of the human genome
- Explain the characteristics and regulation of protein-coding and non-coding genes
- Explain the biogenesis and function of non-coding RNAs and their role in human diseases

- Explain how DNA databases are used in crime scene investigations
- Explain the importance of locating and identifying biological body fluids and principles of laboratory techniques that can be used
- Explain the role of alternative genetic markers relevant in forensic genetics, such as Y-STRs, SNPs and mitochondrial sequence variants
- Discuss quality assurance in a forensic laboratory
- Explain the scientific theory of methods and techniques relevant for genetic analysis
- Apply methods performed during the laboratory exercise, interpret and discuss obtained results in a written report
- Apply statistical analysis on good quality DNA traces and discuss the significance of the results
- Communicate knowledge and skills acquired from the laboratory exercise using relevant scientific language
- Communicate the role of DNA-analysis in the field of criminal justice in particular, but also in the society in general
