Although there were no significantly enriched terms from those databases, there were notable possible WNT-associated terms of "Wnt up-regulation associated oncogenes" (Btg4, Fabp5, Myo5b, Mtf1, Ckap4) and "age at menopause" (Ddx17, Akap13, Slco4a1) at the top of the term lists, suggesting a possible molecular crosstalk between (pre-)GCs and oocytes related to the cause of infertility via defective WNT-signaling (S9 Table). This evidence concerns the gene AKAP13 and Infertility.
