Syndrome de Kearns-Sayre

Syndrome de Kearns-Sayre

Le Syndrome de Kearns-Sayre est une maladie neuromusculaire (myopathie; ophtalmoplégie), due à des délétions de l'ADN mitochondrial : de 1,3 à 8kb (souvent 5kb). Ce sont des délétions très souvent sporadiques, et donc hétéroplasmiques.

Les symptômes apparaissent quand le pourcentage d'ADN mitochondrial anormal par cellule est grand (>60%, cellules musculaires)
