The symbol “#” denotes description of muscular dystrophy severity (mild, moderate, severe, and very severe). The severity is based on age of onset, histopathological severity and time of death. The symbol “?” denotes characterization of mice remains to be published. Description of severity is based on information on https://www.jax.org/.
