13 of these mutations (RET (n = 3) and VHL (n = 10)) were detected by NGS in 13 tumours (see Table 1) and 8 patients had a clinical or previous molecular diagnosis of a germline inherited PCC/PGL gene mutation (NF1 (n = 1), SDHB (n = 5), SDHC (n = 1), and SDHD (n = 1)) that was not covered by the NGS assay. Here, SDHD is linked to adrenal gland pheochromocytoma.
