Feedback and help

Who is this course for?

An undergraduate-level knowledge of biology would be an advantage. If you are new to the field of genetic variation then we recommend that you start with our course Human genetic variation: an introduction to familiarise yourself with some of the key concepts and terms used in the field.

What will I achieve?

By the end of the course you will be able to:

  • recall the purpose and function of the NHGRI-EBI GWAS Catalog
  • recall the type and scope of the data which it contains
  • search the Catalog to identify variants associated with particular traits
  • know where to get help and support on the GWAS Catalog
