Results of screening, replication and combined analyses of the nine SNPs brought forward to the replication.

*Numbers included after quality control of genotyping data.Abbreviations: CHR = chromosome, SNP = single nucleotide polymorphism, OR = odds ratio, CI = confidence interval, n = number of individuals included in the analyses after quality control, HNMT: histamine N-methyltransferase, CLSTN2 = Calsyntenin-2, BTLN2 = Butyrophilin-like protein 2, UTRN = Utrophin, FBXO25 = F-box protein 25.aWhere a SNP is located within a gene, the corresponding gene is underlined.bThe OR is given for OCB negative patients/OCB positive patients.cThe p values are calculated setting age at onset to covariate and are uncorrected for multiple testing.
