MUC20-OT1 is highly correlated with 2PN zygote number and the expression of PRKAR2A, GPC6, SMC5, EIF3A, ITGAV, and PGRMC2. AC123912 is highly correlated with oocyte-retrieved number and the expression of SMC5, EIF3A, PRKAR2A, ITGAV, and PGRMC2. LERFS is a known lncRNA that is highly correlated with oocyte-retrieved number and the expression of SMC5, PRKAR2A, ITGAV, and PGRMC2. The function of these known lncRNAs were mainly studied in cancer research (62, 65). Here, PGRMC2 is linked to cancer.
