Miscarriage is the spontaneous termination of a pregnancy before 24 weeks of gestation. We studied the genome of euploid miscarried embryos from mothers in the range of healthy adult individuals to understand genetic susceptibility to miscarriage not caused by chromosomal aneuploidies. We developed GP , a pipeline that we used to prioritize 439 unique variants in 399 genes, including genes known to be associated with miscarriages. Among the prioritized genes we found STAG2 coding for the cohesin complex subunit, for which inactivation in mouse is lethal, and TLE4 a target of Notch and Wnt, physically interacting with a region on chromosome 9 associated to miscarriages.
自然流产是指妊娠 24 周前的自发性终止。我们研究了来自健康成年个体范围内的母体中染色体正常的自然流产胚胎的基因组,以了解非染色体非整倍体引起的自然流产的遗传易感性。我们开发了 GP ,这是一种用于优先考虑 399 个基因中的 439 个独特变体的管道,其中包括已知与流产相关的基因。在优先考虑的基因中,我们发现了编码黏合复合物亚基的 STAG2,其在小鼠中的失活是致命的,以及 TLE4 是 Notch 和 Wnt 的靶标,与与流产相关的染色体 9 上的一个区域发生物理相互作用。
