Supplementary Material of the article "Association of HCG20 and LINC00243 with schizophrenia and bipolar disorder through the regulation of DDR1 transcript expression in the adult brain dorsolateral prefrontal cortex". Article prepared to be submitted. It contains the results derived from the analyses performed to study whether the long non coding RNAs (lncRNAs) HCG20 and LINC00243 regulate DDR1 transcript expression in brain, particularly: Table S1. Expression levels of the HCG20, LINC02570, DDR1-DT and DDR1 transcripts included. Table S2. Blocks of linkage disequilibrium in the HCG20-DDR1 estimated by PLINK. Table S3. List of SNPs associated with schizophrenia or bipolar disorder in the latest genome-wide and candidate gene association analyses. Table S4. Complementarity hits between lncRNAs and DDR1. Table S5. Correlations between lncRNAs and DDR1 transcripts in healthy controls. Table S6. Mediation analyses between lncRNAs trnascripts, DDR1 transcripts and the diagnoses of schizophrenia and bipolar disorder. Table S7. Differential expression analyses of lncRNAs in schizophrenia and bipolar disorder. Table S8. List of eQTLs for lncRNAs and DDR1 transcripts in the HCG20-DDR1 locus.
