Summary

UConn and Jackson Labs researchers presented preclinical work on three approaches—AAV gene replacement, high-activity protein replacement and adenine base editing—aimed at correcting troponin T2-related dilated cardiomyopathy in laboratory models.

A presenter from UConn Health and The Jackson Laboratory described preclinical progress toward therapies for dilated cardiomyopathy caused by pathogenic variants in troponin T2 (TNNT2), including AAV-mediated gene replacement, engineered higher-activity proteins, and base-editing approaches.

The nut graf: Presenters said each approach has a distinct target population and risk–benefit profile: AAV…
