SLC8A1 and Duchenne muscular dystrophy: Yet other circRNAs were implicated because they showed enriched or reduced expression during expression profiling of mouse and human hearts while mapping to genes previously implicated in cardiomyopathy (for example the ryanodine receptor Ryr2 or Duchenne muscular dystrophy DMD or the sodium/calcium exchanger Slc8a1) [173, 174].
