主要方法:

一个63岁的妇女的病例报告,她患有走路障碍,听力损失和感官多神经病变.
大脑MRI显示中大脑体缩 (蜂鸟标志).
基因检测可以识别异构体DNMT1的21号外突变.
文献审查之前发表的相同突变的病例.

主要成果:

患者的表现模仿了HSAN1E,但是由与ADCA-DN相关的DNMT1突变引起的.
脑部MRI显示出典型的蜂鸟标志,表明中脑缩.
文献审查证实了同一个DNMT1突变的患者中临床特征和放射学发现的显著变异.

结论:

DNMT1突变可以导致广泛的神经疾病,不仅限于先前定义的综合征.
在与DNMT1相关的神经疾病中存在表型和放射性重叠.
结合神经成像和遗传分析对于诊断DNMT1疾病的频谱至关重要.

关键词:

在 DNMT1 中,DNMT1 是一个字符串.这就是HSAN1E.在 exon2121 中.走路的干扰走路的干扰蜂鸟的标志是蜂鸟的标志.

Notch Signaling Pathway

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...
