most common CFTR mutation – delta F508 In a recently reported study, VX-809 was found to be generally safe, but was not able to restore CFTR function in patients with two copies of the delta F508 mutation There is a strong scientific rationale to expect that combining VX-809 with VX770 could be more effective, however An in-

Quel type de mutation mucoviscidose ?
Il existe près de 1 500 mutations de ce gène. La plus fréquente (Delta F 508) est en cause chez 70 % des malades. Selon la nature de la mutation du gène portée par la personne, la mucoviscidose sera plus ou moins sévère. La mucoviscidose est une maladie autosomique récessive.Quelle est l'espérance de vie d'une personne atteinte de mucoviscidose ?
Aujourd'hui, gr? aux progrès de la recherche et à l'amélioration de la prise en charge de cette maladie, l'espérance de vie moyenne d'un patient est comprise entre 40 et 50 ans, alors qu'elle n'était que de 5 ans dans les années 1960.Comment savoir si on porte le gène de la mucoviscidose ?
Deux examens permettent de poser le diagnostic de mucoviscidose : le test à la sueur et l'analyse génétique. Une fois le diagnostic confirmé, un bilan fait le point sur les divers organes atteints par la maladie. Un conseil génétique est délivré.- La mucoviscidose est une maladie génétique. Elle est liée à l'altération d'un gène localisé sur le chromosome 7 : le gène CFTR (pour Cystic Fibrosis Transmembrane conductance Regulator), qui contrôle la synthèse de la protéine du même nom. La protéine CFTR est située dans la paroi cellulaire.
