Premature ovarian insufficiency(POI)is a severe female reproductive disorder that affects 1%of women in general populations(European Society for Human Reproduction and Embryology[ESHRE]Guideline Group on POI et al.,2016).An increasing prevalence up to 3.7%has been reported in a recent meta-analysis(Golezar et al.,2019).POl can lead to infertility or subfertility,as well as a range of complex complications suffering multi-organ systems,seriously threatening women's health and reducing the life *** contrast,POl is a representative heterogeneous disease with multiple *** more than 70 causative POI genes have been identified,the etiology of more than half of the POI patients is still ambiguous(Jiao et al.,2018).Unreported POI causative genes,therefore,remain to be identified.
