Clumping was performed in Functional Mapping and Annotation of Genome-Wide Association Studies (FUMA) version 1.6.150 using an r2 threshold of ≥ 0.6 to define independent significant SNPs, a second threshold of r2 ≥ 0.1 to define lead SNPs, and a maximum distance between LD blocks of 250kb to merge into a locus.
