{Abstract}: BACKGROUND: Hypomyelination with atrophy of the basal ganglia and cerebellum (H-ABC) is a rare genetic disease due to a TUBB4A mutation, with motor features including dystonia. Deep brain stimulation (DBS) can be used to treat dystonia in pediatric populations, although the response is highly variable and preferential toward specific etiologies.
METHODS: A single pediatric subject with H-ABC received DBS using a staged procedure involving temporary depth electrode placement, identification of optimal stimulation targets, and permanent electrode implantation. After surgery, the patient significantly improved on both the Burke-Fahn-Marsden Dystonia Rating Scale and the Barry-Albright Dystonia Scale. The patient's response suggests that DBS can have potential benefit in H-ABC.
CONCLUSIONS: TUBB4A mutations are associated with a variety of clinical phenotypes, and there is a lack of clearly identified targets for DBS, with this case being the second reported instance of DBS in this condition. The staged procedure with temporary depth electrode testing is recommended to identify optimal stimulation targets. The response seen in this patient implies that such a staged procedure may provide benefit in other conditions where DBS targets are currently unknown, including rare genetic or metabolic conditions associated with movement disorders.
