Based on bibliographic data, tissue pattern of expression, biological function of the encoded protein, and a catalog of somatic mutations, we narrowed down the list to five variants in five different genes which may be implicated either in the pathogenesis of PCC (KLHL7 and PKM) or sarcomas (RIPK3, TMEM214 and TFAP2E). This evidence concerns the gene KLHL7 and adrenal gland pheochromocytoma.
