PLAC4 and hydrops fetalis: Between MF vs. AMI and HF vs. MF, we also found several other common differentially expressed lncRNAs (such as PLAC4) and differentially expressed mRNAs including interleukin 1 receptor associated kinase 3 (IRAK3), leucine-rich alpha-2-glycoprotein 1 (LRG1), ribonuclease A family member 1 (RNASE1), FKBP prolyl isomerase 5 (FKBP5), and IKAROS family zinc finger (IKZF2).
