概括
遗传因素对神经发育障碍 (NDD) 有着显著的贡献. 先进的测序技术已经确定了200多个高风险基因,但许多NDD病例仍未被诊断出来,这凸显了进一步研究的必要性.
科学领域:
- 遗传学 遗传学 是一个
- 神经科学是一个神经科学.
- 儿科 儿科 儿科
背景情况:
- 神经发育障碍 (NDD) 是影响社会,认知和情感发展的复杂儿童状况.
- 在NDD病因学中,遗传因素至关重要,已经确定了200多个高风险基因.
研究的目的:
- 审查NDDs遗传发现的进展.
- 讨论基因架构模型和剩余的诊断挑战.
主要方法:
- 大规模的全外基因组测序 (WES) 和全基因组测序 (WGS).
- 识别各种变异类型:新变异 (DNM),副本数变异 (CNV),罕见遗传变异 (RIV) 和常见变异.
主要成果:
- 已经确定了200多个涉及突触功能,转录和表观遗传调节的高风险NDD基因.
- 为NDD遗传架构提出的单基因,寡基因,多基因和全基因模型.
- 很大一部分NDD患者仍然缺乏确定的遗传诊断.
结论:
- 尽管取得了进展,但NDD的遗传基础仍然不完全理解.

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
