Kidney biopsy. a Kidney biopsy histology with H&E staining shows an increased lobular pattern with mesangial expansion in the glomeruli. b Electron microscopy images at 15000x and 60000x magnification reveals broad tubular structures located in subendothelial and mesangial areas of the glomeruli, measuring 30 nm in diameter. The kidney biopsy was consistent with ITG
