Abstract

Background: Premature ovarian insufficiency (POI) is affecting approximately 1% of females and increasingly contributing to female infertility. The etiology of POI is heterogeneous. CHEK1, a critical component of the DNA damage and replication stress response, has recently been linked to female reproductive biology.

Results: We identified a CHEK1 variant c.77C > G; p.A26G in a POI patient through whole-exome sequencing. Protein structure prediction and pathogenicity analysis suggested that the CHEK1 A26G variant may affect protein stability. RNA sequencing results of 293FT cells overexpressing wild-type and A26G CHEK1 revealed altered expression and alternative splicing of genes involved in metabolism and inflammation.

Conclusion: CHEK1 may be involved in ovarian aging and the A26G variant may increase susceptibility to POI.

CHEK1变异是卵巢功能不全的危险因素，通过代谢和炎症相关基因的错误调节。

背景：卵巢早衰（POI）影响着大约1%的女性，并且越来越多地导致女性不孕。POI的病因是不同的。CHEK1是DNA损伤和复制应激反应的关键组成部分，最近被认为与女性生殖生物学有关。结果：我们鉴定出CHEK1变异c.77C > G；通过全外显子组测序在POI患者中发现p.A26G。蛋白结构预测和致病性分析提示CHEK1 A26G变异可能影响蛋白稳定性。过表达野生型和A26G CHEK1的293FT细胞的RNA测序结果显示，代谢和炎症相关基因的表达改变和剪接选择性。结论：CHEK1可能参与卵巢衰老，A26G变异可能增加POI易感性。
