Résumé
Les «SCAs» désignent á présent les ataxies héréditaires de transmission autosomale dominante («ADCAs» dans l’ancienne nomenclature). Les SCAs représentent un groupe de maladies hétérogénes tant sur le plan clinique que génétique [1–3]. La prévalence est de l’ordre de 1 á 4/100 000 et est variable sur le globe. Dans certaines régions, la prévalence est plus élévée (founder effect):
-
SCA1 en Sibérie;
-
SCA2 á Cuba;
-
SCA3 (maladie de Machado-Joseph; MJD) aux Açores;
-
SCA10 au Mexique;
-
DRPLA au Japon;
-
SCA12 en Inde;
-
SCA36 au Japon;
