Abstract

The invention relates to mRNA therapy for the treatment of Citrullinemia Type 2 (“CTLN2”). mRNAs for use in the invention, when administered in vivo, encode human Citrin, isoforms thereof, functional fragments thereof, and fusion proteins comprising Citrin. 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 Citrin expression and/or activity in subjects. mRNA therapies of the invention further decrease levels of biomarkers associated with deficient Citrin activity in subjects, namely ammonia and/or triglycerides.

Claims (4)

1. An mRNA comprising an open reading frame (ORF) encoding the human Citrin polypeptide of SEO ID NO: 1, wherein the ORF is 100% identical to the nucleotide sequence of SEQ ID NO:129.

2. A lipid nanoparticle comprising the mRNA of claim 1 , and a compound having the formula:

or a salt thereof.

3. A method of treating citrullinemia type 2 (CTLN2) in a human subject in need thereof, comprising administering to the human subject an effective amount of the lipid nanoparticle of claim 2 .
