We determined mutations and promoter methylation status of NPM1 using pyrosequencing in 199 samples of myeloid neoplasia including myeloproliferative disorders (MPD). The mutations were present in 4% of chronic myelomonocytic leukemia, but not in other MPD or myelodysplastic syndromes. Promoter methylation was rare, and was found in only three samples of MPD.
我们采用焦磷酸测序法测定了199例髓系肿瘤(包括骨髓增殖性疾病,MPD)样本中NPM1的突变情况和启动子甲基化状态。慢性粒单核细胞白血病患者中有4%存在该突变,但在其他MPD或骨髓增生异常综合征患者中未发现。启动子甲基化情况罕见,仅在3例MPD样本中发现。
