Executive and Attentional Disorders, Epilepsy and Porencephalic Cyst in Autosomal Recessive Cerebellar Ataxia Type 3 Due to ANO10 Mutation

Résumé

BACKGROUND: ANO10 mutations have recently been reported in autosomal recessive cerebellar ataxia type 3 (ARCA3). The objective of this study was to describe the phenotype of 2 siblings with compound heterozygous ANO10 mutations and progressive cerebellar ataxia, epilepsy, and cognitive impairment. A porencephalic cyst was also described in one of them and a coenzyme Q10 deficiency in the other one. METHODS: We performed neurological, neuropsychological, electromyographic, electroencephalic and MRI examinations in 2 siblings with compound heterozygous ANO10 mutations. RESULTS: We reported for the first time the neuropsychological profile of 2 ARCA3 patients showing an adult-onset executive and attentional syndrome. Both presented epilepsy. One of them presented a porencephalic cyst. CONCLUSION: These results suggest that executive and attentional disorders are impaired in ANO10 mutation. In addition, epilepsy and porencephalic cysts were also described in our ARCA3 patients, the cyst thus expanding the clinical phenotype of ARCA3 patients due to ANO10 mutation.
