Feokromocitom je uglavnom benigni tumor kromafinih stanica nadbubrežne žlijezde. Klinička svojstva feokromocitoma pretežno su posljedica prekomjernog lučenja katekolamina, a povišeni krvni tlak najčešća je manifestacija. Razvoj feokromocitoma povezuje se s mutacijama na više od desetak gena. Najčešće se javlja kao posljedica somatskih genskih mutacija, a može biti nasljedan u slučaju embrionalnih mutacija. Ras geni su najčešći onkogeni u ljudskim tumorima. Točkaste mutacije dovode do sinteze Ras proteina bez mogućnosti inaktivacije što uzrokuje neprestanu aktivnost kaskada protein-kinaza aktiviranih mitogenom (MAPK) i signalnog puta fosfatidilinozitol-3-kinaze (PI3-K), zaduženih sa rast, proliferaciju, diferencijaciju i preživljavanje stani...
