Learn the latest statistical methods and software for analysis of genetic association studies

  • Summary

    This advanced course aims to give researchers involved in genetic disease studies a firm grounding in the use of the latest statistical methods and software for analysis of genetic association studies. This includes both small-scale disease-specific studies and large-scale collaborative projects including those that can be used for analysis of multiple complex traits such as UK Biobank.

    The course will cover both theoretical and practical aspects of the design and analysis of such studies. Each topic will include a lecture followed by a practical session in which state-of-the-art statistical software will be applied to relevant datasets. The practical sessions will illustrate the ideas presented in the lectures. All the software used will be freely available so that skills learned can be applied after the course.

    The programme will also include seminars from internationally renowned researchers from the field of complex disease genetics, along with opportunities for participants to discuss their own research projects with course instructors and with each other.

  • Programme

    The programme will include lecture and computer-based practical sessions covering the following topics:

    Introduction to genetic association studies

    • Overview and history of genetic association studies leading up to and including genome-wide association studies.

    Basic association analysis and meta-analysis

    • Single marker association tests (frequentist and Bayesian approaches)
    • Calculation of odds ratios and relative risks
    • Logistic regression
    • Meta-analysis (fixed-effects and trans-ethnic)

    Quality control and population structure

    • Data quality control procedures to avoid the generation of spurious false positives in association studies
    • The confounding effects of population structure on association studies and methods for protecting against these effects
    • Multivariate (principal components) and mixed model approaches 

    Haplotype estimation and genotype imputation

    • Methods for genotype imputation using publicly available reference panels
    • Pre-phasing of haplotypes and imputation based on these inferred haplotypes
    • Frequentist and Bayesian methods of testing association at imputed SNPs and indels
    • Quality control for imputed SNPs
    • Meta-analysis using imputed data

    Heritability and mixed models

    • Concepts of heritability and “missing heritability”
    • Use of linear mixed modelling approaches to partition heritability and to adjust for population substructure and relatedness in genome-wide association studies

    Analysis of rare variants

    • Methods for analysing rare variants from re-sequencing, genotyping and imputation studies via “collapsing approaches”.
    • Burden and dispersion tests of association

    Mendelian randomisation

    • Concepts behind using genetic variants for causal inference in epidemiology
    • Descriptions of the assumptions, limitations and sensitivity analyses of Mendelian randomisation
    • Practical session to apply the above and reproduce examples from the literature

    Post-GWAS interrogation

    • Approaches to integrate genome-wide association signals with multi-omics to understand disease biology

    Practical Sessions
    Lectures are followed by practical sessions using realistic datasets so that students learn how to apply the theory. Students will use a variety of computer programs during the course including: IMPUTE2, SHAPEIT2, SNPTEST2, META, GCTA, FaST-LMM, PLINK.

    Learning outcomes
    On completion of the course, participants can expect to:

    • Understand the general principles, assumptions and basic techniques used in genetic association studies
    • Read and comprehend scientific articles that present results from candidate-gene and genome-wide association studies
    • Analyse genetic data arising from candidate-gene and genome-wide association studies, (including quality control checks, association testing between genotype and phenotype, and post-association fine-mapping of implicated loci to point to likely causal variants, genes and pathways)
    • Perform imputation of variants that have not been directly genotyped, using information from genotyped genetic variants
    • Perform analysis of common and rare variants, accounting for population structure and family data

  • Testimonials

    Feedback from the 2019 course:

    The teachers were excellent. They were able to present very complex topics in distilled and logical sequence that were easy to understand. I also really enjoyed that the teachers were so helpful and accessible during the practicals.

    I loved meeting the other course participants and learning what fields of study they are busy with. All of the course material should definitely be included again. I learned so much!

    The topics covered for this course are very detail and step-by-step analysis practices are really useful and help understanding the actual process of analysis which is really useful. The instructors are experts, they can answer questions in detail and give very useful comments.

    All of the practical sessions were great!
