Project

The MEGASTROKE consortium is a collaboration launched by the International Stroke Genetics Consortium in order to meta-analyze genome-wide association data for stroke and its subtypes.

Experiment summary

The MEGASTROKE study meta-analyzes GWAS data for more than 67,000 stroke cases and more than 450,000 controls from six different ancestries, imputed to either the 1000Genomes or UK10K/HRC reference panels. Ancestry-specific meta-analyses were performed for all stroke and for 4 subtypes, after which trans-ancestral meta-analysis was performed. The European-ancestry subset of this dataset is also available in the Knowledge Portal.
