In addition, SLE samples that contained anti-U1-RNP antibodies had lower eosinophil counts (p = 0.0005), lower lymphocyte counts (p = 0.006), lower monocyte counts (p = 0.03) and lower concentrations of complement protein (C) 3 (p = 0.03) compared to samples from the anti-U1-RNP-negative group. Here, SNRNP70 is linked to systemic lupus erythematosus.
