概括
遗传咨询和对先天性心脏缺陷 (CHD) 的检测在遗传咨询师之间有所不同. 虽然染色体微数组是首选的,但产前顾问更喜欢用于隔离性心血管疾病的旧方法,而不是喜欢使用较新的测序技术的产后顾问.
科学领域:
- 医学遗传学 医学遗传学
- 临床实践 临床实践
- 遗传性疾病 遗传性疾病
背景情况:
- 遗传咨询和检测对于先天性心脏病 (CHD) 管理至关重要.
- 遗传咨询师 (GC) 之间对心血管疾病遗传检测策略的临床实践和偏好仍未得到充分探索.
研究的目的:
- 调查目前的临床实践和综合征性和孤立性冠状动脉疾病 (ICHDs) 的全科医生的测试策略偏好.
- 为了识别产前和产后GCs之间的遗传测试方法的变化.
主要方法:
- 一项在线调查对112名跨越不同专业的GC进行了管理.
- 该调查评估了综合征和ICHD的咨询和测试实践,包括家庭查和首选的遗传测试方式.
主要成果:
- 观察到家庭查建议的变化,产前GC报告ICHD的发病率较低.
- 染色体微阵列 (CMA) 是综合征和ICHD的专业最优先测试.
- 产前GC显示对FISH的偏好更高,对ICHD的型更高,而产后GC则倾向于外体/基因组测序 (约2.6倍高).
- 与产后GC相比,产前GC对iCHD的FISH,型和CMA赋予了更高的实用性.
结论:
- 对于CHDs的GC实践和遗传检测策略表现出显著的变化.
- 结果为当前的GC方法提供了洞察力,并可能为CHD遗传检测协议的标准化提供信息.

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
381
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.

Genetic Screens
5.0K
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...

Animal Mitochondrial Genetics
7.6K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Genome-wide Association Studies-GWAS
13.5K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
