SNPinfo and the PolymiRTS database ( were used to predict miRNAs whose binding activity may be altered because of the SNP location.

  • aThe major allele represents the most frequently occurring allele and serves as the reference allele during modeling.

  • bSNP location derived from Illumina annotation files, HapMap2 data (, and dbSNP (

  • cGenotype data was imputed for all participants by using MACH version 1.0.16 using phased data from HapMap release 22 (genome build 36) derived from individuals with European ancestry (CEU).

  • dPooled OR and 95% CI estimated by using a log-additive model adjusted for study (US-CAN, UK, and POL).

  • ePooled OR and 95% CI estimated by using a log-additive model adjusted for study and the first 2 PCs representing European ancestry.

  • fDDX20 rs19714 is in linkage disequilibrium (LD; r2 = 0.90) with rs197383 identified by Liang and colleagues.

  • gDROSHA rs9292427 is in LD (r2 = 0.98) with rs4867329 identified by Liang and colleagues.

  • hSNP deviates from Hardy–Weinberg Equilibrium (HWE) among all controls with PHWE values of 0.020 for rs607613, 0.040 for rs615435, 0.013 for rs2740349, 0.004 for rs3732133, and 0.034 for rs17147016, respectively.
