| abstract |
The invention relates to mRNA therapy for the treatment of Alagille syndrome (ALGS), mRNAs for use in the invention, when administered in vivo, encode JAGGED 1 (JAG 1), isoforms thereof functional fragments thereof, and fusion proteins comprising JAG1, mRNAs of the invention are preferably encapsulated in lipid nanoparticles (LNPs) to effect efficient delivery to cells and/or tissues in subjects, when administered thereto. mRNA therapies of the invention increase and/or restore deficient levels of JAG1 expression and/or activity in subjects. mRNA therapies of the invention further decrease levels of toxic metabolites associated with deficient JAG1 activity in subjects. |
