PHPS40880 Intro to Genetic Epidemiology

Academic Year 2021/2022

The aim of this module is to give an introduction to genetic epidemiology, in terms of the principles of genetics and to genetic epidemiologic study design, with particular reference to case studies in the field of human medical genetics. The concepts underlying the heritability of traits and measurement of heritability will be covered. The biological and epidemiological principles underlying study designs for the mapping of genes will be explained, with particular emphasis on the genetic architecture of disease: common-disease/common variant, and rare disease / rare variant models will be explored. The role and mechanisms of gene-environment interactions in health and disease, and complex genetic architecture encompassing genetic heterogeneity and epistasis will be explored with reference to case studies from the literature.

Learning Outcomes:

On completion of this module students will be able to:
• Understand the principles of genetic epidemiology and the features which distinguish it from other epidemiologic research
• Understand the aims of, and conceptual similarities and differences between different study designs
• Identify the range of possible genetic architectures which can underlie a trait or a disease
• Identify a variety of approaches to investigate associations between genes/genetic variants and complex diseases in gene mapping studies, and understand potential confounders of these associations
• Appreciate the role and possible mechanisms by which genetic and environmental risk factors can interact to increase risk of disease

Approaches to Teaching and Learning:
This module consists of an online distance course in genetic epidemiology for human genetic researchers. The predominant modes of delivery are short video segments and guided and self-directed reading. Active learning is encouraged through formative asynchronous group discussions online, formative guided exercises and formative self-assessments with feedback. Cumulatively the students work towards a final summatively assessed literature review, drawing together all the strands they have learned over the trimester.
