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).
On the assessment of available evidence, the authors concluded that moderate evidence exists for an association between the BLK rs13277113, rs2248932 variants and SLE.
