Title

(EN) IDENTIFICATION OF A JAK2 MUTATION IN POLYCYTHEMIA VERA

(FR) IDENTIFICATION D'UNE MUTATION DE JAK2 IMPLIQUEE DANS LA POLYGLOBULIE DE VAQUEZ

Abstract

(FR) La présente invention concerne le variant V617F de la protéine tyrosine kinase JAK2, ledit variant étant responsable de la Polyglobulie de Vaquez. L'invention se rapporte également à une méthode de diagnostic en première intention de l'érythrocytose et de la thrombocytose permettant de les rattacher à des syndromes myéloprolifératifs ou à la détéction dans les syndromes myéloprolifératifs du variant JAK2 V617F permettant de les reclasser dans un nouveau groupe nosologique et à l'identification d'inhibiteurs spécifiques et de siRNA.
