Despite its atypical renal presentation, our cohort universally demonstrated immunological evidence of SLE: 100% ANA positivity (18/18 evaluated), 94.1% (16/17) anti-dsDNA antibody positivity, and 93.3% (14/15) hypocomplementemia (Table 1 and Supplementary Table 4). This evidence concerns the gene BTG3 and systemic lupus erythematosus.
