Additionally, given that dopamine clearance also occurs via various other mechanisms elsewhere in the brain, delineation of the contributing roles of other dopamine regulators beyond the DAT to BD symptomology (e.g. norepinephrine transporter, catechol-O-methyltransferase, monoamine oxidase B) will be vital moving forward [79]. The gene discussed is SLC6A3; the disease is Behcet disease.
