Overview

You will be able to explain how human populations evolved using evidence supported by the fossil record as well as advances in sequencing technologies. You will form an understanding of human genome sequence diversity, and how different types of pathological sequence variations cause genetic disease. Topics include: human evolution, population migrations, population sequence diversity, evolution of genetic disease, analysis of genetic disease in population-based research, diagnosis of genetic disease, molecular basis of genetic disease, personalised medicine. The balance of topics in this unit is approximately 1/3 evolution, 2/3 genetic disease.

Aims

The study of human genetic complexity and disease is a rapidly expanding field driven by advances in new technologies which facilitate large-scale projects to catalogue human genetic variation. These large-scale sequencing projects have revealed support for our understanding of human evolution and population migrations based on the fossil record.  These studies have also revealed the extent of human genome sequence variations.  However, understanding the link between genetic variation and the resulting phenotype presents challenges, as is apparent from large-scale association studies. This unit will explore how studying human genome sequences can inform our understanding of genetic disease and evolution.

Learning outcomes

Students will be able to:

  • Explain how human populations evolved using evidence supported by the fossil record as well as advances in sequencing technologies.
  • Describe the types and frequency of sequence variants in human genomes
  • Describe large-scale human genome sequencing projects.
  • Explain the use of association studies to find polygenic disease variants.
  • Explain the molecular pathology of monogenic genetic diseases.
  • Describe methods for diagnosing genetic diseases.
  • Explain how identifying sequence variants influences medical treatments.
  • Develop literature searching skills and use of publically available genetic databases for coursework.

Syllabus

Fees and funding

Additional expenses

The year studying abroad is an integral part of the course and must be completed. Some costs, such as tuition fees, are substantially lower. Other costs can vary and are not included in the tuition fee. For example, living costs may be higher or lower than the UK, and there are travel-related costs to consider, such as paying for a passport, visa fees, health insurance, and (if needed) vaccinations.

Policy on additional costs

All students should normally be able to complete their programme of study without incurring additional study costs over and above the tuition fee for that programme. Any unavoidable additional compulsory costs totalling more than 1% of the annual home undergraduate fee per annum, regardless of whether the programme in question is undergraduate or postgraduate taught, will be made clear to you at the point of application. Further information can be found in the University's (PDF document, 91KB).

Scholarships/sponsorships

Students participating in placements outside the UK may be able to apply for funding from the depending on eligibility. Priority will be given to students from low income households.
