概括

婴儿遗传性血管 (HAE) 的早期诊断具有挑战性. 建议对父母变异进行基因测试,而不是C1抑制剂测试,以准确检测儿童的HAE.

科学领域:

免疫学免疫学免疫学
遗传学遗传学是一个
儿科儿科儿科

背景情况:

新生儿遗传性血管 (HAE) 诊断因不成熟的补体系统而复杂化.
婴儿中C1抑制剂 (C1INH) 和C4水平可能暂时低,模仿缺乏.
早期的HAE发作可以在出生时发生,需要可靠的诊断方法.

研究的目的:

为了调查婴儿遗传性血管的诊断挑战.
评估C1抑制剂测试与早期HAE检测的基因测试的实用性.
介绍典型的补充蛋白在婴儿正常化的对比例子.

主要方法:

一个案例报告,两名孩子的母亲患有C1抑制剂缺乏症 (HAE).
功能性C1抑制剂测定在婴儿和幼儿时期的多个时间点进行.
基因分析用于识别后代的致病变体.

主要成果:

婴儿最初的C1抑制剂测定显示出正常的抑制活性.
基因检测证实了母亲的病原性HAE相关基因变异在两个孩子的存在.
随后的监测显示了病态C1抑制剂的减少,证实了HAE诊断.

结论:

仅仅依赖C1抑制剂测定可以导致婴儿HAE.AE的错误诊断.
对索引父母的致病变体进行遗传检测是早期检测儿童HAE的更可靠方法.
这种方法有助于在儿童群体中及时管理和干预HAE.

Genetic Screens

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...
