The red cell acid phosphatase (ACP1) gene, which encodes a low-molecular-weight phosphotyrosine phosphatase, has been suggested as a common genetic factor of autoimmunity. In the present study, we aim to investigate the possible association of ACP1 with the susceptibility of systemic lupus erythematosus (SLE). A total of 1,546 SLE patients and 1,947 healthy individuals from 4 Caucasians populations were included in the present study. Four single-nucleotide polymorphisms (SNPs) were genotyped in this study: rs10167992, rs11553742, rs7576247, and rs3828329. ACP1*A, ACP1*B, and ACP1*C codominant ACP1 alleles were determined using 2 of the SNPs and analyzed. After the meta-analysis test was performed, a significant association of rs11553742*T was observed (p(pooled) = 0.005, odds ratios = 1.37 [1.10-1.70]), retaining significance after multiple testing was applied (p(FDR) = 0.019). Our data indicate for first time the association of rs11553742*T with increased susceptibility in SLE patients.
