Our observations provide new information on the genotype-phenotype relations of MAOA/B and EFHC2 genes involved in the contiguous deletions of Norrie disease.Based on the case of our observation, contiguous deletion with only one of the MAO genes (MAOB) may not cause psychomotor disability, and deletion of EFHC2may not contribute to epilepsy.

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
