Genes in the turquoise module were enriched for the longevity regulating pathway (adjusted p value = 0.0047), GnRH (Gonadotropin-releasing hormone) signaling pathway (adjusted p value = 0.0042), glioma (adjusted p value = 0.0126), cholinergic synapse (adjusted p value = 0.0091), human cytomegalovirus infection (adjusted p value = 0.0126), and endocytosis (adjusted p value = 0.0126). Here, GNRH1 is linked to central nervous system cancer.
