The Fourth Consensus Report of the Dementia with Lewy Bodies Consortium, published in 2017 (1), lists two indicative biomarkers of DLB in neuroimaging: uptake of dopamine transporter in single photon emission computed tomography (DaT-SPECT) and that of meta-iodobenzylguanidine (MIBG) in myocardial scintigraphy. The gene discussed is SLC6A3; the disease is Lewy body dementia.
