Abstract excerpt
Approximately 20% of dopa-responsive dystonia (DRD) cases remain genetically unresolved. Using whole-genome sequencing, we identified two TH variants in a young DRD patient, including a novel deep intronic variant. Minigene assays confirmed that this variant causes aberrant splicing. The patient exhibited an atypical disease progression compared with typical TH-associated DRD cases, presenting with generalized...
