概括

先天性镜像运动障碍,以非自愿的镜像运动为特征,与DCC基因突变有关. 一项家庭研究发现了DCC基因的无意义突变,该突变发生在四个受影响的个体中,跨越了三代.

科学领域:

遗传学遗传学是一种遗传学.
神经学神经学
发育生物学发展生物学

背景情况:

先天性镜像运动障碍涉及身体一侧的非自愿运动,反映了相反侧的自愿运动.
这种情况主要与DCC网-1受体 (DCC) 基因的突变有关.

研究的目的:

在一个多代家庭中调查先天性镜像运动障碍的遗传基础.
为了在受影响的家庭中确定导致疾病的特定基因突变.

主要方法:

一个3岁儿童患有先天性镜像运动障碍的案例研究.
跨越三代人的家族史评估,注意到类似的非自愿移动.
对受影响的家庭成员进行四重整体外组测序 (WES) 分析.

主要成果:

三代同一家庭的四个人出现了先天性镜像运动障碍.
所有临床症状的个体都携带了DCC基因的无意义突变.
症状的严重程度各不相同,指数病例表现出比祖母更显著的表现.

结论:

先天性镜像运动障碍可以在一家人中跨世代表现出来.
DCC基因的无意义突变是先天性镜像运动障碍的可能原因.
这项研究突出了镜子运动及其遗传模式的遗传基础.

Sex-linked Disorders

Sex-linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Mechanism of Ciliary Motion

Mechanism of Ciliary Motion

The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...
