- Disease or Syndrome
Oocyte/zygote/embryo maturation arrest-8 (OZEMA8) is characterized by female infertility due to failure of the fertilized ovum to undergo zygotic cleavage (Zheng et al., 2020).

- Disease or Syndrome
Oocyte/zygote/embryo maturation arrest-9 (OZEMA9) is characterized by female infertility due to oocyte meiotic arrest at metaphase I in most patients. Abnormal zygotic cleavage has also been observed (Zhang et al., 2020).

- Disease or Syndrome
Oocyte/zygote/embryo maturation arrest-21 (OZEMA21) is characterized by female infertility caused by zygote arrest due to pronuclei fusion failure (Zhang et al., 2021).
