L'IDH1 est l'une des trois isocitrate déshydrogénases. Son gène est IDH1 situé le chromosome 2 humain.

En médecine

[modifier | modifier le code]

La mutation de son gène augmente la synthèse du 2-hydroxyglutarate avec un effet cancerigène[5]. Le mécanisme de cette dernière serait une hyperméthylation de l'ADN modifiant l'expression de certains gènes, dont celui du TET2[6], intervenant dans la différenciation cellulaire.

Ces mutations sont décrites dans plusieurs types de tumeurs cérébrales[5], dans certaines leucémies myéloïdes aiguës[7]et dans certains types de tumeurs osseuses comme le chondrosarcome.

Cible thérapeutique

[modifier | modifier le code]

L'ivosidénib est un inhibiteur de la forme mutée de la protéine[8] qui a une certaine efficacité sur les leucémies aiguës myéloblastiques réfractaires ou récidivantes[9].
