Genetic research about SLE confirms an association between copy number variations (CNV) and SNP within TLR7 gene locus and the susceptibility of SLE (Lau et al., 2005; Shen et al., 2010; Kawasaki et al., 2011; Wang et al., 2014; Ortiz 2019). This evidence concerns the gene TLR7 and systemic lupus erythematosus.
