As shown by ALE plots (Fig. 5c), higher EAAT2 levels (% of control) were associated to a relevant linear decrease in schizophrenia probability, higher l-Asn levels (nmol/g of tissue) were associated to a relevant linear increase in schizophrenia probability whereas a non-linear relationship was detected with respect to the rest of the molecules. This evidence concerns the gene SLC1A2 and schizophrenia.
