ST341: Statistical Genetics

Lecturer(s): Dr Jere Koskela

Important: If you decide to take ST341 you cannot then take ST418. Bear this in mind when planning your module selection. Recall: an integrated Masters student must take at least 120 CATS, of level 4+ modules over their 3rd & 4th years.

Prerequisite(s): ST115 Introduction to Probability, ST218 Mathematical Statistics A, ST219 Mathematical Statistics B

Commitment: 3 hours of lectures per week. This module will run in Term 2.

Content: The module will introduce students to probabilistic models and statistical methods used in the analysis of genetic data.

Aims: Students will gain a basic understanding of the rapidly growing field of genome-wide association studies, and be exposed to practical applications of common statistical tests.

Objectives: By the end of the course students should be able to

  • describe simple discrete-time reproductive models and use them to derive the standard coalescent model
  • use coalescent theory to relate DNA sequence variation to genealogical history
  • evaluate, from simple datasets, evidence for linkage disequilibrium and disease assocations using basic association tests
  • discuss the wider issues involved in applying association tests to whole genomes.

Assessment: 80% by a 2-hour exam. 20% by coursework. Coursework will consist of two written assignments worth 10% each.

Deadlines: Assignment 1: week 7 of Term 2, Assignment 2: week 10 of Term 2.

Feedback: Feedback on both assignment 1 and 2 will be returned after 2 weeks, following submission.
