Table 1 The list of diseases of the central nervous system (CNS) that can be linked to metabolites influenced by TE insertions

From: Somatic transposition in the brain has the potential to influence the biosynthesis of metabolites involved in Parkinson’s disease and schizophrenia

  1. The expected numbers of such metabolites (+/− SD), and P were estimated by Monte Carlo simulations, which show how many such metabolites would be expected if the same number of TE insertions as observed by Baillie et al. (16) were distributed across the genes of the human metabolic network randomly. Hypothyroidism is also included, because it shares metabolites with several diseases of the CNS, like dopamine, serotonin, homovanillate or L-Tyrosine.
