On the assessment of available evidence, the authors concluded that moderate evidence exists for an association between the BLK rs13277113, rs2248932 variants and SLE.
We confirmed that SNP rs2248932 in BLK gene was significantly associated with SLE (P = 1.41 x 10(-8) for the allele frequency, Odds ratio [OR] = 0.74, 95% confidence interval (CI): 0.66-0.82).The association of BLK in Chinese SLE patients was consistent with a dominant model (P = 8.88 x 10(-9), OR = 0.69, 95% CI: 0.61-0.79).
