概括
遗传咨询师支持针对性染色体异位症 (SCAs) 的非侵入性产前检测 (NIPT),但对微删除/微重复综合征 (MMSs) 和单基因疾病 (SGDs) 表现出不同的热情. 经验影响了在SGD测试中对NIPT的建议.
科学领域:
- 生殖遗传学和产前诊断.
- 临床遗传学和遗传咨询.
- 分子诊断和查技术.
背景情况:
- 非侵入性产前检测 (NIPT) 已被确立为自体形形状瘤.
- 扩大NIPT的应用包括性染色体积症 (SCAs),微删除/微复制综合征 (MMSs) 和单基因疾病 (SGDs).
- 遗传咨询师对这些扩展的NIPT适应症的意见是不同的.
研究的目的:
- 评估遗传咨询师对NIPT对SCAs,MMS和SGD的实用性,准确性和适当性的看法.
- 确定影响遗传咨询师推扩大NIPT使用的因素.
- 了解目前对非传统指示的NIPT采用情况.
主要方法:
- 在14个国家的51名遗传咨询师中进行的一项跨部分基于网络的调查 (2024年10月至12月).
- 一个18项调查问卷评估了NIPT对SCAs,MMS和SGD的感知效用,分析准确性和临床适当性.
- 用描述性统计和顺序逻辑回归来分析反应和人口统计学关联.
主要成果:
- 对SCAs (86%) 的高感知效用,其次是SGD (80%) 和MMS (67%).
- 对测试准确性的信心较低,特别是对于MMS (55%).
- 对SCA的常规NIPT有强烈的支持 (88%),对SGD有条件的支持 (47%是常规的,45%是特定的环境),对MMS的支持较低.
- 专业经验显著预测了为SGDs推NIPT的意愿 (OR=1.15每年,p=0.017).
结论:
- 遗传咨询师强烈支持NIPT用于SCAs,并对MMS和SGD测试表示有条件的支持.
- 建议的变化,特别是SGD的变化,与专业经验有关.
- 这些发现强调了对扩大NIPT应用的持续教育,强大的验证数据和有针对性的政策制定的需要.

What is Genetic Engineering?
Overview
CRISPR
Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced Short...
Genetic Screens
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which result in visible changes...

Pharmacogenomics: Identification of New Drug Targets
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
Human Genetics
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.
The complex relationship between genetics and psychology is observable through common biological components such...

Behavioral Genetics and Its Designs
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.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...
