Lesion and FLCN mutation in case 2. a CT scan reveals a mass in the right kidney (arrow). b Histopathology of the resected tumor shows tumor cells with transparent, slightly reticulated cytoplasm with prominent cell membranes (chromophobe renal cell carcinoma). c The patient has a deletion of CCT (c.770-772delCCT) in exon 7 of the FLCN gene, which results in deletion of the 257th serine residue (p.257delS). The deleted bases are underlined in the normal sequence
