BACKGROUND
RUNX1/AML1, which is a Runt family transcription factor critical for normal hematopoiesis, is frequently mutated or translocated in a broad spectrum of hematopoietic malignancies.
FINDINGS
We describe here the case of a 54-year-old female developed acute myeloid leukemia with a t(5;21)(q21;q22). Transcriptome sequencing identified the chromodomain-helicase-DNA-binding protein 1 gene, CHD1, as a novel partner gene of RUNX1. Furthermore, the patient was found to harbor FLT3-ITD mutation, which might collaborated with CHD1-RUNX1 in the development of acute myeloid leukemia.
CONCLUSIONS
We have identified CHD1 as the RUNX1 fusion partner in acute myeloid leukemia with t(5;21)(q21;q22).
背景
RUNX1/AML1是一种对正常造血至关重要的Runt家族转录因子，在多种造血系统恶性肿瘤中经常发生突变或易位。
研究结果
我们在此描述了一名54岁女性患急性髓系白血病且伴有t(5;21)(q21;q22)的病例。转录组测序确定染色质结构域解旋酶DNA结合蛋白1基因（CHD1）为RUNX1的一个新的伙伴基因。此外，发现该患者携带FLT3-ITD突变，其可能在急性髓系白血病的发生发展中与CHD1-RUNX1相互作用。
结论
我们已确定CHD1是伴有t(5;21)(q21;q22)的急性髓系白血病中RUNX1的融合伙伴。
