Clinical and biological impact of TET2 mutations and expression in younger adult AML patients treated within the EORTC/GIMEMA AML-12 clinical trial

Abstract: We assessed the prognostic impact of TET2 mutations and mRNA expression in a prospective cohort of 357 adult AML patients < 60 years of age enrolled in the European Organization For Research and Treatment of Cancer (EORTC)/Gruppo Italiano Malattie Ematologiche dell' Adulto (GIMEMA) AML-12 06991 clinical trial. In addition the co-occurrence with other genetic defects and the functional consequences of TET2 mutations were investigated. TET2 mutations occurred in 7.6 % of the patients and were an independent mark… Show more

“…Studies have been carried out of the various DMRGM and other genes reported as indicating an unfavorable prognosis in AML. [18][19][20]22,23,[25][26][27][28][29][30] Our group has also reported that AML with DMRGM at onset is associated with a high frequency of FLT3-ITD at relapse and has an unfavorable prognosis. 31 However, since comprehensive gene mutation analysis using a next-generation sequencer is costly, there have so far been few reports on DMRGMbased prognostic analysis covering a large number of cases.…”

“…The same worse prognosis is observed when associated with a DNMT3A mutation. They also show that patients with low TET2 mRNA expression, albeit without mutation, have also a decrease of their overall survival (Aslanyan et al, 2014).…”

“…В настоящее время подтверждена важная роль TET в регуляции экспрессии генов через модификацию хроматина в промоторных регионах [117]. Соматические мутации в гене TET2 обнаружены у 7-10 % взрослых и у 1,5-4 % детей с ОМЛ [118][119][120][121]. Мутации TET2 сопро-вождаются потерей функции гена [118,122] и приводят к гипометилированию соответствующих участков генома [123].…”

“…Соматические мутации в гене TET2 обнаружены у 7-10 % взрослых и у 1,5-4 % детей с ОМЛ [118][119][120][121]. Мутации TET2 сопро-вождаются потерей функции гена [118,122] и приводят к гипометилированию соответствующих участков генома [123]. Было показано, что эти мутации сопровождаются статистически значимо низким уровнем 5-гидрометилци-тозина и высоким уровнем метилирования промоторов генов по сравнению с нормальным клетками, что под-тверждает участие мутации TET2 в патогенезе лейкоза [123].…”
