Furthermore, patients with ANCA-associated vasculitis had higher glomerular expression of K7, K18, and K19 compared to patients with FSGS (FSGS vs. ANCA K7: −2.512, 95% CI −4.385 to −0.6385, p = 0.0041, K18: −2.599, 95% CI −4.449 to −0.7486, p = 0.0024, K19: −3.217, 95% CI −5.357 to −1.076, p = 0.0011, respectively). This evidence concerns the gene KRT7 and anti-neutrophil cytoplasmic antibody-associated vasculitis.
