To the editor: Oocyte maturation arrest (OMA) is one of the major causes of recurrent failure of assisted reproductive therapies. Since the phenotype was first reported in 1990, the genetic causes underlying this phenotype had been largely unknown until 2016, when mutations in TUBB8 (MIM: 616768) were reported to cause oocyte metaphase I (MI) arrest [1]. Subsequently, biallelic mutations in mRNA-binding protein PATL2 were reported to cause oocyte germinal vesicle (GV) arrest [2]. TRIP13 (MIM: 604507) was the third gene identified to be responsible for OMA, and biallelic pathogenic mutations of TRIP13 could lead to oocyte MI arrest [3]. However, the abovementioned gene mutations contribute to approximate 30–40% patients with defect in oocyte maturation, leaving the remaining 60% of cases with yet unknown genetic determinations.Recently, biallelic mutations in CDC20 (MIM: 603618), encoding a co-activator of anaphase-promoting complex (APC), were reported in five unrelated families with multiplicity phenotypes, including abnormalities in oocyte maturation and early embryonic development [4]. In that article, one patient from a consanguineous family who displayed the
