概括
多基因胚胎查 (PES) 可以估计后代的疾病风险,但新的模型显示潜在的风险降低可能被高估. PEStimate应用程序有助于评估PES的影响,考虑植入失败等因素.
科学领域:
- 生殖医学和遗传学
- 流行病学建模和生物统计学
- 生物信息学和计算生物学
背景情况:
- 多基因胚胎查 (PES) 旨在通过选择具有较低遗传倾向的体外受精 (IVF) 胚胎来降低后代患复杂疾病的遗传风险.
- 目前的PES结果预测依赖于流行病学模型,通常是复杂的,需要先进的计算,以前没有考虑植入失败.
- 准确估计PES的有效性对于医疗保健提供者,患者和决策者做出明智决策至关重要.
研究的目的:
- 开发和介绍PEStimate,这是一个新的在线应用程序,用于预测单一疾病风险的多基因胚胎查结果.
- 引入更新的 PES 流行病学模型,将胚胎植入失败的可能性纳入其中,解决先前模型中的局限性.
- 为探索各种参数对PES有效性和潜在风险降低的影响提供一个用户友好的工具.
主要方法:
- 开发一种新的 PES 流行病学模型,包括胚胎植入失败.
- 创建PEStimate,一个免费可访问的在线应用程序 (闪亮的应用程序) 实现新的模式.
- 在PEStimate中包含可调节的参数,例如胚胎数量,活产率,疾病流行率,遗传性,遗传预测器准确性,选择方法和父母遗传信息.
主要成果:
- 该研究的更新模型表明,以前可能存在过度估计与PES相关的风险降低.
- PEStimate提供了带有和没有PES的后代疾病风险的预测,以及风险降低的可视化.
- 该应用程序允许用户探索PES结果对各种遗传和生殖参数的敏感性.
结论:
- PEStimate为利益相关者提供了一个有价值的,易于使用的工具,以实证地研究多基因胚胎查的潜在好处和危害.
- 将植入失败纳入PES建模表明,需要对疾病风险降低幅度的期望进行修订.
- 该工具有助于就像PES这样的先进生殖遗传技术的临床效用和社会影响进行知情讨论.

Genetic Screens
5.6K
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...

Polygenic Traits
68.9K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...
