In addition to the quick search for SNP, gene and variant in the homepage, there are three advanced query modules, including "Search Gene & Marker", "Search Study" and "Search G-E Interaction". "Search Gene & Marker" module is to query association result by genetic markers (SNP, other variants) or related gene name. User can also further filter the result by setting "No. of Gene's Association Result" in different result categories ("Significant", "Non-significant" and "Trend") or by study related attributes, including "Reference Type", "Reported Trait", "Traumatic Type", "Diagnosis", "Study Type" and "Published Year". "Search Study" module aims to query interested studies by "Reference Type", "Reported Trait", "Traumatic Type", "Diagnosis", "Study Type", "Published Year" and "PMID". "Search GxE Interaction" is a specialized module based on the importance of environmental variables in pathogenesis of PTSD and consistent with genetic studies trends. Users can use gene names and environment variables as input to query the research result of gene-environment interaction studies. Figure 1 shows different data types and data connections.
