发展生物学发展生物学
分子生物学分子生物学

背景情况:

微删除综合征是由于染色体删除太小而导致的遗传疾病,对于标准的型定型来说太小了.
这些综合征呈现出复杂,可变的表型,原因是多个基因同时丧失.
将基因哈普洛缺陷与复杂的表型联系在一起的机制尚未完全理解.

研究的目的:

在模型生物体中研究大型微切除的表型后果.
用CRISPR/Cas9基因组编辑生成的新型微删除等位基因的特征.
建立一个模型系统来研究微删除表型的复杂性和变异性.

主要方法:

使用CRISPR/Cas9基因组编辑来诱导Caenorhabditis elegans中类似微删除的等位基因.
生成的微删除等位基因被映射到V染色体并进行平衡.
断点结点被精确地定义,并对同卵性突变物进行了表型效应分析.

主要成果:

一个可行的微删除等位基因删除了32个编码蛋白质的基因被恢复和特征.
同性异性突变体表现出母体效应致死性,多核胚胎,子宫瘤,阴道缺陷和运动失调.
成年同卵性突变体的寿命缩短,经常死于爆裂.

结论:

许多基因的同时删除可以导致具有复杂的,类型的表型的可活生物体.
这种C. elegans模型提供了一个强大的系统来剖析微删除综合征的遗传和发育基础.
进一步的研究可以利用这种模型探索基因相互作用和微删除表型的透性.
