Sažetak


Uvod. Ishemijski moždani udar (IMU) je heterogeni poremećaj koji može biti uzrokovan genetskim faktorima rizika i faktorima sredine. Poremećaji koagulacije mogu biti uzročnici u 1-4% slučajeva IMU, naročito kod bolesnika kod kojih se IMU dogodi u mlađem životnom dobu. Prikaz bolesnika. Prikazan je slučaj bolesnika koji je u mlađem životnom dobu razvio IMU nepoznatog uzroka. Urađeni su biohemijski, imunološki i testovi za trombofiliju kao i sekvenciranje DNK sa ciljem da se utvrdi molekularna patologija koja je mogla biti u osnovi moždanog udara kod tog bolesnika. Testovima za trombofiliju utvrđeno je da je bolesnik homozigotni nosilac mutacija PAI-1 4G/5G i MTHFR C677T. Dodatnom genetičkom analizom otkriveno je prisustvo nedavno opisane F2 c.1824C>T genske varijante, koja se nalazi u poslednjem egzonu gena za protrombin i za koju je prethodno pokazano da izaziva hiperprotrombinemiju, hipofibrinolizu i izmenjeni fenotip fibrinskog ugruška. Zaključak. Naši rezultati ukazuju na to da bi nova F2 c.1824C>T genska varijanta mogla imati sinergistički efekat sa PAI 4G/4G i MTHFR 677TT genotipom u nastanku fibrinskog ugruška sa izmenjenim fenotipom, koji se odlikuje tankim, gusto upakovanim fibrinskim vlaknima, što čini ugrušak manje podložnim fibrinolizi i povećava rizik od nastanka IMU u ranijem životnom dobu.
