A number of genetic studies have identified STAT4 SNPs with links to SLE in Caucasian populations for example, rs7582694 [37], rs7601754 and rs7574865 [38], and rs7582694 [155], in addition to rs7574865 and SLE in a Northern Han Chinese population [39]. The gene discussed is STAT4; the disease is systemic lupus erythematosus.
