20. We found significant negative correlations regarding the expression of the genes COMT, MAOB, DRD4, DRD5 and FOS, indicating that increased schizotypy coincides with higher levels of dopaminergic dysregulation on the mRNA-level. PMID: 24630741
21. Our results confirmed that SNPs in DRD4 and COMT, but not DBH or MAOB are associated with autism and ADHD in small, ethnically homogeneous groups of non-related male Caucasians. PMID: 24210742
