Dear Editor,Of all human tumors,pheochromocytomas and paragangliomas(PPGLs)have the highest heritability *** 15%of PPGLs harbor mutations in genes encoding tricarboxylic acid(TCA)cycle-related enzymes that cause oncometabolite accumulation and drive tumorigenesis via metabolic adaptation to hypoxia and global hypermethylation[1].The dihydrolipoamide S-succinyltransferase(DLST)gene was recently described as a new PPGL susceptibility gene[2].
