Description
This module explores the purpose of clinical genetic testing and its impact on patient care. You will learn how genomic data flows from the patient to the laboratory, then to the clinician, and back to the patient, giving you insight into the complete diagnostic pathway. You will examine how genetic tests are designed, including assay types, gene selection and the resulting outputs, such as variant annotation and clinical classification.
You will develop an understanding of the genetic principles that underpin evidence-based assessment of variant effects, and learn how to use multiple database sources and clinical literature in variant classification. This includes evaluating the advantages and limitations of automated classification tools ClinVar and ClinGen. You will also explore how laboratory classifications are integrated with clinical interpretation and where to find best-practice guidelines, such as the ACMG framework and the UK ACGS guidelines, to determine the clinical significance of results.
The module will introduce you to the multidisciplinary team (MDT) process, including how MDT meetings support clinical variant interpretation in practice. You will consider the role of genetic counselling and issues related to family screening, as well as the ethical and legal considerations associated with clinical genomics. Topics include patient data security, population diversity and its impact on variant interpretation, changes in variant classification over time, reporting of incidental findings, and cascade testing of relatives.
Learning outcomes
By the end of this module you will be able to:
- Interpret evidence (including population, phenotype, inheritance, predictive and functional data) used for variant classification.
- Evaluate a range of genomic variant reports in human disease.
- Apply relevant national and international guidelines to classify genomic variants.
- Discuss the strengths and limitations of variant interpretation in an MDT setting.
