中心点:

部分血液恶性肿瘤患者携带罕见的剪接体基因突变,这种突变与未知疾病相关。

很多罕见的甚至是私有的剪接体基因突变产生热点突变的分子表型,并可能致病。

摘要:

编码RNA剪接因子SF3B1、SRSF2和U2AF1的基因在克隆造血和多种肿瘤疾病中常发生错义突变。大多数“剪接体”突变影响特定的热点残基,导致剪接变化,促进疾病的病理生理。但部分患者携带影响非热点残基的剪接体突变,这些残基对疾病的潜在作用尚未明确。

近期,Pangallo等人对各种罕见的和私有的剪接体突变进行了系统的描述,以推断它们可能的疾病相关性。

研究人员利用同基因细胞系和患者原发组织发现,14个研究的SRSF2和U2AF1中的罕见的和私有的突变导致了明显的剪接改变,包括热点突变引起的外显子和剪接位点部分或完全表型改变,或模仿两个同时发生的热点突变驱动的“双重”表型。

本研究数据表明,许多罕见的和私有的剪接体突变促进疾病发生,并说明了分子检测的用途,通过推断新发现的突变的潜在疾病相关性,为精准医疗提供信息。
