Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease characterized by autoantibody production. It is a multifactorial disease with a variety of clinical manifestations and it is found most often in women. Genetic factors have been associated with the development of SLE. Copy number variations (CNV) of genes as well as epigenetic factors such as microRNAs (miR) have been involved. The aim of this study was to correlate the expression of miR-3148 with CNV of TLR7 gene in Mayan women with systemic lupus erythematosus from Yucat�¡n. We studied 100 women diagnosed with SLE and 100 healthy women as a control group. The CNV and miR-3148, was determined by real-time PCR (Q-PCR) using TaqMan probes. The results indicate that 17% of the patients present more than two copies of the TLR7 gene, with respect to the controls. Correlation was found between CNV and TLR7 mRNA (r = 0.4080, n = 0.0016) and between miR-3148 and mRNA (r = 0.5950, p = 0.0002) in the patients, suggesting that both variables can be risk markers to develop the disease.
