KEGG pathway analysis showed that cell cycle, Fanconi anemia pathway, DNA replication, homologous recombination, progesterone-mediated oocyte maturation, oocyte meiosis, and cellular senescence were the most significantly altered pathways in the STAG2 high expression group (P-adjusted < 0.05; Figures 5C and 5D). This evidence concerns the gene STAG2 and Fanconi anemia.
