One of them had αMPO-ANCA positive MPA with crescentic GN (Fig. 5b) and the other patient had αPR3-ANCA positive GPA with focal necrotizing GN (Fig. 5c) and a repeat biopsy obtained after approximately nine months showing signs of previous GN and no evidence of active inflammation (Fig. 5d). Here, ATRAID is linked to ganglioneuroma.
