Abstract

We describe the case of a chronic myeloid leukemia (CML) patient with a rare atypical e18a2 :: transcript. The generation of this transcript was explained by a detailed molecular analysis, including the identification of both chromosomal breakpoints (:: on der(22) and :: on der(9)) at the genomic level. The use of a cryptic splice site in intron 1 of led to the generation of an in-frame :: fusion transcript. The diagnostic difficulties caused by this atypical variant and its implications for diagnostic routine are discussed.

摘要

我们描述了一例慢性粒细胞白血病(CML)患者,其存在一种罕见的非典型e18a2 :: 转录本。通过详细的分子分析,包括在基因组水平鉴定两个染色体断点(22号染色体衍生染色体上的 :: 和9号染色体衍生染色体上的 :: ),解释了该转录本的产生。在 内含子1中使用一个隐蔽剪接位点导致了一个读码框内的 :: 融合转录本的产生。讨论了这种非典型变体引起的诊断困难及其对诊断常规的影响。
