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.

|# 4||Learning outcome 3,4||
Explain how to choose and apply major bioinformatic resources for clinical diagnostics in this disease/service area and how their results are integrated with other lines of evidence to produce clinically valid reports.
|# 5||Learning outcome 3,4||

You must complete:
- 2 case-based discussion(s)
- 2 of the following DOPS/ OCEs:
|Use the ensemble variant effect predictor tool to annotate a VCF file See if any genes in a CMV are present in the OMIM morbid database||DOPS|
|Annotate a splice site mutation using more than one algorithm, and explain their relative strengths weaknesses.||DOPS|
|Interpret missense analysis results e.g. SIFT and PolyPhen||DOPS|
|For a disease select the appropriate LSDB i.e BRCA BIC etc. Select based on ease of integration and quality||DOPS|
|Present findings of the interpretation of a missense variant to a MDT meeting||OCE|
In the context of both human and microbes:
- Annotate variation data in the context of a specific genetic investigation.
- Develop variation data to inform a testing strategy for a specific patient population.
- Develop an analysis strategy for a new service.
- 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.
Academic content (MSc in Clinical Science)
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.

Clinical experiential learning is the range of activities trainees may undertake in order to gain the experience and evidence to demonstrate their achievement of module competencies and assessments. The list is not definitive or mandatory, but training officers should ensure, as best training practice, that trainees gain as many of these clinical experiences as possible. They should be included in training plans, and once undertaken they should support the completion of module assessments and competencies within the e-portfolio.
- Observe a range of clinical consultations where patients with genetics disorders meet with health professionals to discuss how clinical bioinformatics can be applied in the care pathway.
- With permission, identify a patient or family with a genetic disorder and discuss the impact of that genetic disorder on the quality of life of the patient and/or family with an appropriate clinical professional and reflect on how this experience will influence your future practice.
- Attend and contribute to teaching sessions where Clinical Scientists are being instructed in the correct use of existing bioinformatic analysis procedures and review/report the procedures, the use of standard operating procedures and the process of interaction with Clinical Scientists.
- Attend and contribute to multidisciplinary meetings at which the results of genetic investigations are discussed and reflect on the process, the weighting placed on different types of data, and the effect on patients’ results and care pathway.
- Visit other pathology settings where clinical bioinformatics and genomics are increasingly being used to develop strategies for identification, diagnosis and treatment, and reflect on the future contribution of clinical bioinformatics to pathology services.
