SNRNP70 and systemic lupus erythematosus: In SLE patients with positive anti-Sm antibody, the frequency of SS genotype was significantly higher than LL/LS genotype (p = 0.014, OR = 2.385, 95% CI 1.188–4.785) (see Figure 1(c)); the same result was also found in SLE patients with positive anti-U1RNP antibody (p = 0.025, OR = 2.46, 95% CI 1.108–5.461) (see Figure 1(d)).
