基因检测对于诊断多系统性疾病 - - 跨甲基素氨基粉症 (ATTR) 至关重要. 识别像p.Gly77Arg这样的特定突变可以揭示家族联系和疾病进展的多样性.
科学领域:
- 心脏病学 心脏病学
- 遗传学 是一个遗传学.
- 神经学 神经学
背景情况:
- 晶氨基粉症 (ATTR) 是一种被诊断不足的多系统性疾病,已知有140多种突变.
- 在ATTR中器官的参与取决于特定的遗传突变而有很大差异.
- ATTR可以表现出各种症状,包括神经病变和心力衰竭.
研究的目的:
- 调查基因测试在诊断和理解跨氨化症中的作用.
- 强调识别特定ATTR突变及其家族影响的重要性.
- 为了强调与不同的ATTR突变相关的可变器官热带性.
主要方法:
- 一位患有神经病变和充血性心力衰竭的老年男性患者的案例研究.
- 诊断程序包括心声图和内肌心脏活检.
- 进行基因检测以确定引起的突变 (c.229G>A,p.Gly77Arg).
- 对家庭成员进行了连续的基因测试.
主要成果:
- 这位患者被诊断为 transthyretin amyloidosis. 这位患者被诊断为 transthyretin amyloidosis.
- 基因检测显示了一种罕见的误解突变 (p.Gly77Arg),此前仅在另一个国际病例中报告过.
- 级联测试在多个家庭成员中发现了相同的突变,表现出不同的疾病阶段.
- 这些发现强调了基因分析在ATTR诊断中的重要性.
结论:
- 基因检测对于所有被诊断患有ATTR的人来说是必不可少的,无论年龄如何.
- 这种p.Gly77Arg突变显示出可变的器官热带性和家族内的疾病透性.
- 早期遗传鉴定有助于家庭查和ATTR的个性化管理.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
