Hyperkinetic Movement Disorder

In 2 unrelated patients with axial hypotonia, developmental delay and a hyperkinetic movement disorder, a missense mutation was found in codon 209 of the GNAO1 gene. From the still scarce literature on GNAO1 mutations, a clear genotype-phenotype correlation emerged. From the 26 patients reported thus far, 12 patients had epileptic encephalopathy, and 14 had a developmental delay and a hyperkinetic movement disorder. All but 1 of the latter patients had missense mutations in GNAO1 codon 209 or 246, which thus appear to be mutation hotspots. At least 2 sibling pairs showed that the recurrence risk after 1 affected child with a GNAO1 mutation might be relatively high (5-15%), due to apparent gonadal mosaicism in the parents.

Preliminary Study

Costello syndrome (CS), a rare syndrome with multisystemic involvement inherited as a dominant trait, is characterized by developmental delay, coarse facial appearance, cardiac defects including hypertrophic cardiomyopathy, skin abnormalities, brain complications, and a predisposition to certain malignancies. The musculoskeletal system is particularly affected in CS, with peculiar orthopedic anomalies that impact posture and gait. Dystonia has been recently documented to contribute to abnormal postures and musculoskeletal anomalies characterizing CS, suggesting the possible use of pharmacological treatments to treat these complications. We report the case of a child affected by CS displaying a particularly severe musculoskeletal involvement with dystonic posture especially in the arms and legs. The Movement Disorder-Childhood Rating Scale (MD-CRS) and a gait analysis were used to assess clinical patterns of hyperkinetic movement disorder and dystonia. The child was further treated with trihexyphenidyl for six months with a final dosage of 14 mg. MD-CRS and gait analysis assessments provided evidence for a significant improvement of posture and the related musculoskeletal problems with no side effects. Our preliminary study report provides first evidence that pharmacological anti-dystonia treatment significantly improves movement and posture disorders in patients with CS. Further studies enrolling larger cohorts of patients should be performed to validate these preliminary observations.

The authors report the cases of 2 young male patients (aged 16 and 26 years) with dystonic cerebral palsy of unknown origin, who developed status dystonicus, an acute and persistent combination of generalized dystonia and chorea. Both patients developed status dystonicus after undergoing general anesthesia, and in 1 case, after administration of metoclopramide. In attempting to control this acute hyperkinetic movement disorder, multiple medication trials failed in both cases and patients required prolonged intubation and sedation with propofol. Bilateral deep brain stimulation of the globus pallidus internus (4 and 2 months after the onset of symptoms in the first and second case, respectively) produced immediate resolution of the hyperkinetic movement disorder in each case. Deep brain stimulation provided persistent suppression of the dystonic movement potential after a follow-up of 30 and 34 months, respectively, as demonstrated by the reemergence of severe dystonia during the end of battery life of the implantable pulse generators that was readily controlled by exchange of the generators in each case.
