While it is undeniable that novel diagnostic tools such as dopamine transporter (DAT) scans, meta-iodobenzylguanidine (mIBG) scintigraphy, cerebrospinal fluid (CSF) protein analysis, and positron emission tomography (PET) ligand marker imaging provide significant information that greatly improves diagnosis of movement disorders, they are not readily available or easy to perform, especially in developing countries. Here, SLC6A3 is linked to movement disorder.
