Similarly, Rotman et al. described a pauci-inflammatory thrombogenic vasculopathy with deposits of C3d, C4d, C5b-9, and MASP2 within the microvasculature and positive SARS-CoV-2 envelope/spike glycoprotein and ACE2 receptors in biopsy specimens [85]. The gene discussed is MASP2; the disease is vascular disorder.
