Overview

AAV-TNNT1 is an adeno-associated virus (AAV) vector-based gene therapy designed to treat TNNT1-associated Nemaline Myopathy, also known as Amish Nemaline Myopathy (ANM). Developed by the University of Massachusetts Chan Medical School and the Clinic for Special Children, the therapy delivers a functional copy of the TNNT1 gene, which encodes the slow skeletal muscle isoform of troponin T. To prevent potential cardiotoxicity and off-target effects in fast-twitch myofibers, the vector incorporates microRNA target cassettes for de-targeting, restricting TNNT1 expression specifically to slow-twitch (type I) myofibers.
