Germline mutation of the succinate dehydrogenase subunit genes, SDHA, SDHB, SDHC or SDHD, is associated with increased risk for paraganglioma (PGL), pheochromocytoma (Pheo), gastrointestinal stromal tumor (GIST) and renal cell carcinoma [15–18]. Here, SDHD is linked to hereditary clear cell renal cell carcinoma.
