GWAS study design, genotyping technologies and user needs have advanced since the initial design of the Catalog. It is essential that the Catalog adapts to contain the most relevant and up-to-date studies and association results. Studies using large-scale targeted/non-genome-wide arrays, including the Metabochip, Immunochip and Exome arrays, and genotyping by sequencing are currently not included in the Catalog. Following feedback from our users we have plans to extend the scope of the Catalog to include all large-scale association studies and all SNP-trait associations, regardless of P-value. This, coupled with programmatic access, will vastly improve the utility of the Catalog for large-scale meta-analyses of published GWAS data with increased power to identify causal loci.
