概括

在微小病患者的30.1%中发现了耳部异常的家族病史. 微和前耳道标记/洞通常在家族中同时发生,这表明这些先天性耳部疾病的遗传成分很重要.

科学领域:

医学遗传学医学遗传学
耳鼻喉科耳鼻喉科耳鼻喉科
发展生物学发展生物学

背景情况:

微小症是一种先天性外耳异常,缺乏明确的原因,具有潜在的遗传和环境影响.
对于遗传咨询和临床管理来说,了解微菌的发病过程至关重要.
之前的研究尚未就微型病的遗传模式达成明确的共识.

研究的目的:

调查诊断为微病的患者家庭病史的频率和模式.
分析微症严重程度,相关异常和遗传特征之间的关联.
探索微和相关耳朵异常的潜在遗传性质.

主要方法:

我们对672名来自专门诊所的微型病患者进行了回顾性分析.
经过三代人的先天性耳朵异常家族史被细致地记录下来.
统计测试 (皮尔森奇平方,费舍尔精确) 用于评估微菌特征和遗传模式之间的相关性.

主要成果:

在研究的微病患者中,有30.1%的家庭有耳环异常病史.
家庭病史的发病率与微病的程度 (P=0.001) 有显著差异.
患有前耳道标签或穴位的患者与简单微小病 (24.1%,P<0.001) 相比,表现出更高的家族发病率 (38.3%).

结论:

较低等级的微生菌表现出更高的积极家族史的频率.
微小病患者有显著的亲属有 preauricular标签或坑的流行.
这种同时发生的情况表明,微和前耳膜异常是共同遗传缺陷的相关表现,表明存在相当大的遗传风险.

Microtubules in Signaling

Microtubules in Signaling

The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...

Animal Mitochondrial Genetics

Animal Mitochondrial Genetics

Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Chromosomal Theory of Inheritance

Chromosomal Theory of Inheritance

In 1866, Gregor Mendel published the results of his pea plant breeding experiments, providing evidence for predictable patterns in the inheritance of physical characteristics. The significance of his findings was not immediately recognized. In fact, the existence of genes was unknown at the time. Mendel referred to hereditary units as “factors.”
