Advanced Clinical Bioinformatics (SBI120)

10 credits

Aim of this module

Advances in genomics are leading to a better understanding of genetic variation and the role that such variation plays in human health and infectious disease. Such insights are important in predicting inherited disease risks, understanding and classifying cancer, predicting individuals’ responses to drug treatment, or better understanding the spread of drug-resistant pathogens. This module will develop the trainee’s fundamental understanding of genetic variation and its role in disease. It will also build on the trainee’s bioinformatics knowledge of the wide range of tools and resources that are used in bioinformatics to capture this knowledge, and how such tools are used by Clinical Scientists to support patient-centred care, diagnosis and treatment. A strong emphasis will be placed on ethical and confidentiality issues with such sensitive data.

This module will enable the trainee to apply their knowledge of genetic variation and its role in disease in the context of bioinformatics and the wide range of tools and resources that are used in clinical bioinformatics to capture data and support patient-centred care, diagnosis and treatment. A strong emphasis will be placed on ethical and confidentiality issues with such sensitive data. An awareness of the impact of interpretations given on clinical and public health action should be paramount when communicating the analysis of data to multi-disciplinary teams.

 For some trainees this will involve applying their knowledge of pathogen variation in bacteria and viruses and how this relates to inference of transmission and resistance to apply bioinformatics tools and algorithms to support outbreak analysis and pathogen characterisation.

In the context of both human and microbes:

  1. Annotate variation data in the context of a specific genetic investigation.
  2. Develop variation data to inform a testing strategy for a specific patient population.
  3. Develop an analysis strategy for a new service.
  4. Advise a service with respect to the bioinformatic requirements of a new service and the strategy to deliver appropriate and clinically relevant data to support patient care.

Important information

The academic parts of this module will be detailed and communicated to you by your university. Please contact them if you have questions regarding this module and its assessments. The module titles in your MSc may not be exactly identical to the work-based modules shown in the e-portfolio. Your modules will be aligned, however, to ensure that your academic and work-based learning are complimentary.
