In contrast, the inducible 960 CUG expanded repeat EpA960/HSA-Cre-ERT2 (+tam) mouse model, which shows both sequestration of MBNL1 and elevated levels of CELF1 protein in skeletal muscle, has a more complete DM1 phenotype including muscle wasting [17]. The gene discussed is MBNL1; the disease is myotonic dystrophy type 1.
