GWAS: Genotyped using Illumina platforms with >550K genome-wide association study (GWAS) SNPs. The samples included in previous GWAS study.

IC: Subjects genotyped using Immunochip (IC) array.

Subjects genotyped using both GWAS platform and Immunochip array

Number of SNPs within the region [chromosome 6 bps 28911802 – 33813043 (HG19 map)] used for analyses.

Number of SNPs genotyped in region that overlap the reference sets used for imputation.
