Additionally, we did not identify any P/LP variants in BUB1, BUB1B, KASH5, KHDC3L, MEI1, NLRP7, REC114, and TOP6BL genes, which are implicated in conditions that cause rare syndromic forms of RPL such as recurrent hydatidiform mole, oocyte/zygote/embryo maturation arrest, and mosaic variegated aneuploidy syndrome. This evidence concerns the gene REC114 and hydatidiform mole.
