Our study conducted KEGG pathway enrichment analysis for the genes associatedwith spontaneous abortion at p<0.05 in MR results, includingENTPD1, CD209, FLRT2, GLRX2, GLTPD2, HBZ, MYORG, LMNB1, LILRA4, MMP9, NELL1,SEMA3G, SELL, TMEM132C, TNFRSF1B, TNFAIP6, EMC4, NDC80, PRRG1, MUL1), as shownin Figure 1. This evidence concerns the gene LILRA4 and abortion.
