BANK1 and systemic lupus erythematosus: Interestingly, we noted that the GWAS-associated SNP (4:101829919 G/A; BANK1R61H, MAF 0.25, odds ratio (OR) = 1.4 [95% confidence interval (CI): 1.3–1.5], p = 3.74 × 10−10), tags a common BANK1 haplotype12,14 and is likely in linkage disequilibrium with the low-frequency BANK1W40C in our SLE cohort (Supplementary Fig. 2); both SNVs occur within exon 2.
