研究人员发现,罕见的,有害的非编码变体与遗传通用 (GGE) 有关. 这凸显了研究非编码DNA区域对于研究的重要性,因为在这些领域,新的遗传发现是有限的.
科学领域:
- 遗传学 遗传学 是一个
- 神经学 神经学
- 生物信息学是一种生物信息学.
背景情况:
- 的遗传性仍然在很大程度上无法解释,尽管进行了大量的队列研究,但发现的新变种有限.
- 罕见的非编码变异,可以影响基因表达,在研究中被研究不足.
研究的目的:
- 调查罕见的非编码有害变异与的关联,特别是遗传通用 (GGE).
- 用深度学习算法评估非编码变体对大脑组织表达的功能影响.
主要方法:
- 分析了来自247名患者和377名对照组的全基因组测序 (WGS) 数据.
- 深度学习算法ExPecto被用来预测大脑组织中非编码变体的表达变化.
- 在病例和对照人群之间对罕见非编码有害变异的负担进行了比较分析.
主要成果:
- 罕见的非编码高度有害的变体在遗传通用患者中显著丰富.
- 与对照组相比,在非获得的焦点 (NAFE) 或整体队伍中没有观察到显著的丰富.
- 这项研究确定了罕见的非编码有害变体和GGE之间的特定关联.
结论:
- 罕见的非编码有害变体与有关,特别是GGE.
- 研究非编码区域对于推进研究至关重要,尤其是在发现新的遗传因素方面.
- 需要更大的全基因组测序队列来对这些发现进行更高分辨率的调查.
