positive.code: The GWAS Catalog contains SNP-by-SNP and SNP-by-environment interaction studies as long as the SNPs analysed meet our criteria of being genome-wide (see www.ebi.ac.uk/gwas/docs/methods). For both types of study, the term “interaction” is added in parenthesis to the reported trait. For SNP-by-environment interaction studies, the environmental component is also included in the reported trait e.g. “Lung cancer (smoking interaction)” or “Bone mineral density (gender interaction)”. For SNP-by-SNP interaction studies the term “SNP x SNP interaction” is added in parenthesis.
  To identify interaction studies, you can search for “interaction” in both the GWAS Catalog search and the download spreadsheet.
  
  ==== [[faq-B12]]12. How can I search for targeted or exome array studies and associations?
  
  You can enter the genotyping technology of your interest in the search bar, e.g. “targeted genotyping array”, “exome genotyping array”. This will return any study and association that uses that specific genotyping technology as reported by the authors. You can also filter results by genotyping technology as described below.
  
  
negative.code: ==== [[faq-C6]]6. What is the difference between filtering by a trait via the trait dropdown and doing a search by clicking on that trait in the results?
  Filtering via the trait dropdown limits the search results to studies that have the selected trait(s) as their reported trait, as well as any associations identified in those studies. Clicking on a trait link does a complete new search for that term, searching across all fields, including title and sample descriptions, so you may get additional results, not just studies annotated with the search trait.
  
  ==== [[faq-C7]]7. How do I filter results from targeted or exome array studies?
  
  You can filter your results using the genotyping technology dropdown on the left side of the page. The filter is inclusive, allowing users to retrieve studies, associations and traits that use at least the selected genotyping technology. You can also click on multiple genotyping technologies to display all studies and associations and traits that use at least one of the selected filtering terms, or both.
