The most significantly enriched pathways included Epstein-Barr virus infection (q = 7.0 × 10−13), osteoclast differentiation (q = 3.4 × 10−7), proteasome (q = 1.9 × 10−7), the neurotrophin signaling pathway (q = 1.1 × 10−6), ERBB signaling pathway (q = 2.0 × 10−6), influenza-A (q = 1.0 × 10−5), T cell receptor signaling pathways (q = 1.3 × 10−5), and the MAPK signaling pathway (q = 5.7 × 10−5, S6 Table). This evidence concerns the gene BDNF and Epstein-Barr virus infection.
