Genetic Analysis of Mendelian and Complex Disorders
18–24 July 2018
Wellcome Genome Campus, Hinxton, UK
This intensive, residential, computational course is aimed at scientists
actively involved in genetic analysis of rare (Mendelian) or complex
human traits who anticipate using state-of-the-art statistical analysis
techniques on genetic data collected on related and unrelated
The programme provides a comprehensive overview of the statistical
methods currently used to map disease susceptibility genes in humans and
non-model organisms with an emphasis on data collected on families or
populations (which should often be considered a collection of large
This is a small residential course, with a low student to instructor
ratio, personalized attention, and the instructors actively involved
throughout the week. Students present on their own research to the group
and receive constructive criticism particularly pertaining to study
design and analysis. This course is unique among statistical genetics
courses in that it concentrates on approaches that capitalize on families
or a combination of families and unrelated individuals in the post-GWAS
Why does this course emphasise family data?
In the GWAS and post-GWAS era, gene mapping has concentrated on analysis
of unrelated individuals due to the simplicity and convenience. However,
these approaches tend to treat any relatedness among individuals as a
nuisance to be adjusted away rather than a benefit to be exploited.
Furthermore, researchers are increasingly aware that the use of unrelated
individuals has limitations that family data overcome. Family studies
have many advantages in gene mapping, such as:
- They are extremely powerful in situations where unrelated individuals lack power (e.g., when rare variants underlie the etiology) since related affecteds are more likely to share the same disease predisposing gene than unrelated affecteds
- They overcome confounding factors such as population stratification and allow better modeling of environmental factors
- They allow the examination of a wealth of nuanced genetic models; and (4) they provide ways to rule out artifacts and false associations that can plague genetic analyses. This course will enable participants to make better use of their data that may include related individuals.
During this course, discussions of the latest statistical methodology are
complemented by practical hands-on computer exercises using
state-of-the-art software. The statistical principles behind each method
will be carefully explained so that participants with a non-statistical
background can understand and better interpret their results. Note,
however, that the bioinformatics pipelines for calling variants from next
generation sequencing data are not covered; the focus of this course is
on the downstream analysis of the called variants.
This course is aimed primarily at advanced Ph.D. students and post-docs
who are early in their careers, whose projects involve data that could be
analysed by the methods covered in this course. Since we emphasize
methods for handling family data, there is a preference for candidates
who have some family data or who are likely to have access to family data
in the future. Programming experience is not required, but
candidates without prior experience with the Unix/Linux/Mac command line
will be expected to read through a tutorial on this topic prior to the
course (available at http://www.ee.surrey.ac.uk/Teaching/Unix/).
Feedback from the 2017 course
“The amount of opportunity we had for discussion and interaction with
one another was probably one of the best aspects – the opportunity to
converse with so many great minds is priceless.”
“The course was very well organized, the teachers are very easy going,
friendly and accesible, and makes all much easier.”
“Thank you for an informative and enjoyable course. It was very well
organised and well taught. The instructors were very hands on and
available throughout the course.”
“This was a truly excellent course – all the instructors who were
involved in the teaching sessions were excellent.”
“Great course. I learned a lot, albeit not necessarily the thing I
expected to learn. I feel like a better scientist, even more so than I
feel like a better geneticist.”
“The course was very useful as it helped place in a better context a lot
of the genetic analysis techniques I had started learning about but was
unsure about how to apply them in my research.”
The programme will discuss fundamental issues needed to increase success
in gene mapping studies including:
- Why families?
-Contrasting family and population study designs
-Practical aspects of collecting family data
- Association analysis in samples of unrelated and related individuals
-Linear mixed models (LMM, aka variance components)
- Linkage analysis as an effective tool for gene mapping in the post-GWAS era
- Quality control strategies:
-When only using unrelateds
-When families are included
- Using families in order to move beyond simple genetic models
- Haplotyping using GWAS and sequencing data
- Analysis of rare traits using sequencing data from families
- Risk prediction, meta-analysis, and other post-GWAS analysis using families
Teaching will take the form of lectures by instructors and invited expert
speakers, informal tutorials, hands-on computer sessions, and analysis of
example disease data sets. Our interactive and intensive educational
program will enable researchers to better carry out sophisticated
statistical analyses of genetic data, and will also improve their
interpretation and understanding of the results. All the software used is
freely available, so that skills learned can be easily applied after the
course. After the course, participants will be provided with a
virtual machine copy of the computer used during the course, so they can
easily explore back at their home institutions the computer exercises and
example data sets in greater detail.
To ensure that participants get personalized constructive advice,
particularly pertaining to the study design and analysis plan for their
own research, each participant will give a short presentation about his
or her own research project, either planned or in progress.
On completion of the course, participants should be able to:
- Evaluate the use of family and population data in genetic analyses and determine in what ways family data would be useful in their own research projects.
- Have a deeper appreciation of optimal study design and power, and to be able to critically evaluate the design and power of their own research projects.
- Evaluate current best statistical approaches and conditions under which their use is appropriate or inappropriate, and thus determine the most suitable statistical methods for their own research projects.
- Be able to use current software to analyse real family and population data and to interpret the results, including quality control, association and linkage testing, and fine mapping approaches.
