| Gene |
SLC6A3 |
| Chromosomal Location |
5p15.33 |
| Allelic Variant 1 |
; DOPAMINE TRANSPORTER DEFICIENCY SYNDROME; DTDS |
| Identified Mutation |
c.1408T>A; The dopamine transporter (DAT), which is encoded by the SLC6A3 gene, mediates the active reuptake of dopamine from the synapse and is a principal regulator of dopaminergic neurotransmission. The SLC6A3 gene has been implicated in human disorders such as parkinsonism, Tourette syndrome, and substance abuse (Vandenbergh et al., 1992). |

| Remarks |
Clinically affected; onset of symptoms within the first few weeks after birth; diagnosed at 10 months of age with infantile Parkinsonism and dystonia; DAT1 deficiency; normal head size and growth; cranial nerves: symmetric smile but mild, mask-like facies; atrophy/wasting of temporalis muscles; slightly sunken eyes; no tongue atrophy or fasciculation; continual rapid dystonic contractions of both arms; more static asymmetric dystonic posturing of lower extremities (left flexor bias, right extensor bias); hands often held open, but fisted during opisthotonic episodes; central tone is poor (head lag when pulled to sit, vertical slip-through); tendon reflexes are not increased; left foot in dystonic plantar grasp; no Babinski reflex elicited; cautionary weight gain; severe dysphagia secondary to dystonia; genetic testing by Sanger sequencing; homozygous mutations in SLC6A3 gene; allele 1: 1408T>A and c.1409A>G; allele 2: 1408T>A and c.1409A>G; assistive devices: wheelchair, G-tube feeding. |
