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). The gene discussed is PRKAR2A; the disease is cancer.
