This strain was generated through n-ethylnitrosourea (ENU) mutagenesis program. It has fewer revertant muscle fibers than the mdx strain in skeletal muscle. These mice exhibit histopathological features similar to mdx including fibrosis, fatty infiltration and necrosis in the diaphragm that progresses with age.
