In this study, both radiological findings including pulmonary fibrosis or ILD suggesting MPA and pulmonary nodules, mass, and cavitation indicating GPA critically contributed to the reclassification of OvSD/pSS/MPA and OvSD/pSS/GPA as described in Table 2 and Table 3 and Tables S1 and S2. The gene discussed is GYPA; the disease is interstitial lung disease.
