SLC6A3 Gene
Solute Carrier Family 6 Member 3 (Dopamine Transporter) (SLC6A3) is a gene involved in dopamine reuptake that has been studied in relation to immune function, metabolism, and chronic illness. Variants in SLC6A3 may influence how the body responds to infection, inflammation, and long-term recovery.

What is the SLC6A3 gene?
SLC6A3 encodes solute carrier family 6 member 3 (dopamine transporter), a protein involved in dopamine reuptake. It belongs to the Neurotransmitter category and is part of the Neurological & Cognitive Function biological cluster. SLC6A3 encodes the dopamine transporter (DAT), which removes dopamine from synaptic clefts and is essential for dopaminergic signal termination.
Biological role and pathway
SLC6A3 is involved in the dopamine reuptake pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Neurological & Cognitive Function cluster work together to maintain balanced function across interconnected biological systems.
Variants in genes within this pathway may influence an individual's predisposition to altered function in these systems — particularly under conditions of physiological stress such as viral infection or prolonged illness.
SLC6A3 and Long COVID / ME-CFS research
DAT variants affecting dopamine clearance may influence dopaminergic dysfunction and cognitive fatigue in Long COVID brain fog.
