概括
新生儿基因组查 (NBS) 在不同人群中是可行的,可以识别超出当前方法的可治疗疾病. 进一步的研究将评估对健康结果的概括性和影响.
科学领域:
- 基因组学
- 公共卫生
- 新生儿医学
背景情况:
- 传统的新生儿查 (NBS) 在识别所有遗传疾病方面存在局限性.
- 在不同种族和族群中对NBS的基因组测序的可行性尚未得到充分理解.
研究的目的:
- 在多元化的纽约市人口中评估基因组NBS的可接受性,可行性和结果.
- 报告"对所有新生儿罕见疾病的基因组统一查" (GUARDIAN) 研究的初步结果.
主要方法:
- 涉及156种早期遗传疾病的基因组测序和99种神经发育障碍的可选查.
- 在纽约市招收了4000名来自不同种族背景的新生儿.
- 收集家长报告的种族和民族数据.
主要成果:
- 获得72.0%的同意率, 参与者反映了纽约市的多样性.
- 测序成功完成率为99.6%.
- 报告了3.7%的检查阳性率, 确定目前没有NBS的情况.
结论:
- 针对性基因组测序在不同人群中是可行的.
- 基因组NBS可以通过确定其他可治疗的疾病来补充现有的查.
- 需要进一步的研究来确认其通用性和临床影响.

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

4.9K
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...
