To identify additional SLE-associated variants, we performed an imputation-based association analysis in and around IFIH1 using MACH [22] with reference data from AA (207 controls) and EA (594 controls) using genotyping data from the ImmunoChip (Figure 2B, 2E and Tables S6, S7). The gene discussed is IFIH1; the disease is systemic lupus erythematosus.
