Background:

Parkinsonism (PD) is occasionally seen in several types of spinocerebellar ataxia (SCA). Mutations in SCA gene have been reported in the patients of parkinsonism without ataxia.

Methods:

We examined spinocerebellar ataxia type 12 mutation in 877 PD and 199 multiple system atrophy (MSA) patients.

Results and Conclusions:

No patients showed abnormal SCA12 expansion. It suggests that PD and MSA are not associated with SCA12 and it is not necessary to screen SCA12 in PD and MSA patients.

Résumé:

RÉSUMÉ:Contexte:

On observe parfois du parkinsonisme dans plusieurs types d’ataxies spinocérébelleuses (SCA). Des mutations du gène de la SCA ont été rapportées chez des patients présentant du parkinsonisme sans ataxie.

Méthodes:

Nous avons recherché ces mutations chez 877 patients parkinsoniens et chez 199 patients atteints d’atrophie multisystémique.

Résultats et conclusions:

Aucun patient n’était porteur d’une expansion anormale du gène de la SCA de type 12. Ceci porte à croire que la maladie de Parkinson et l’atrophie multisystémique ne sont pas associées au gène de la SCA 12 et qu’il n’est pas nécessaire d’en faire le dépistage chez les patients atteints de la maladie de Parkinson et de l’atrophie multisystémique.
