概括

遗传因素,包括BMP15基因变异,与早产卵巢缺陷 (POI) 有关. 这项研究澄清了BMP15变体的致病性,发现同胞性功能丧失变体是致病性的,大多数异胞性误解变体是良性的.

科学领域:

遗传学是一个遗传学.
生殖生物学生殖生物学
基因组学就是基因组学.

背景情况:

过早卵巢衰竭 (POI) 影响大约1%的女性在40岁之前.
遗传因素是POI发展的重要贡献者.
在POI中BMP15基因变异的作用和影响仍然不完全理解.

研究的目的:

调查BMP15基因变异在POI/卵巢储量减少 (DOR) 患者队列中的致病性和透性.
将POI患者中BMP15变异的频率与一般人群进行比较.
确定与POI相关的特定BMP15变异,并评估它们的遗传模式.

主要方法:

在500名POI/DOR患者中,对BMP15基因的整个编码区域进行下一代测序.
与一般人口数据相比,分析BMP15鉴定变异的频率,考虑种族.
分离分析以确定家族内变异的遗传.

主要成果:

确定了11种不同的BMP15变异,其中包括一种致病性无意义变异.
在POI队列中,超过10% (10.8%) 携带至少一种BMP15变异.
与对照组相比,POI患者中出现了两个错误变体的显着过度代表性;确定了一种同卵性功能丧失变体,并从健康的父母遗传.

结论:

大多数异合体BMP15误解变体可能是良性的.
同胞性功能丧失的BMP15变体是POI的致病原体.
一些BMP15误解变体可能代表具有低透性的不确定的意义的变体,主要在同卵性或复合异卵性状态中有害.

关键词:

在BMP15中,BMP15是BMP15中的一个.透性透性透性过早的卵巢衰竭是早产的

Oogenesis

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
