MAX and adrenal gland pheochromocytoma: Using MAX mutation genotype-phenotype analysis, we compared the occurrence rate of PCC (P = 0.170), metastatic PCC (P = 0.985), PGL (P = 0.647), PA (P = 0.905), other-NET (P = 0.779), and non-NET (P = 0.762), and the mean age at diagnosis at the presentation of PCC (P = 0.990) between patients with missense and non-missense mutations.
