In this study we present a three-phase, multi-tissue design: Top) a Discovery Phase involving a MWAS in a large set of blood samples as well as a number of exploratory analysis; Middle) an Overlap Phase where we test for enrichment of MWAS overlap between blood and brain; Bottom) a Replication Phase where all sites in the significant overlap are followed up with “look-up replication” in two independent brain collections from BA10 and in the second brain tissue (BA25) from the original brain MWAS sample.
