摘要

Solute Carrier Family 6 Member 3 (SLC6A3) gene encodes the sodium-dependent dopamine transporter, terminating dopamine action by high-affinity reuptake into presynaptic terminals. Pathogenic SLC6A3 variants cause dopamine transporter deficiency syndrome (DTDS), an autosomal recessive complex movement disorder (MD). Classic early-onset and atypical later-onset forms are known.1,2 In classic DTDS, infants manifest non-specific findings (irritability, feeding difficulties, axial hypotonia, and delayed motor development), followed by hyperkinetic MD (chorea, dysto-nia, ballismus, and orolingual dyskinesia). Over time, parkinsonism-dystonia develops. Secondary orthopedic, gastrointestinal, and respiratory complications are common.
