Comparison of dy and dy2J, Two Alleles Expressing Forms of Muscular Dystrophy in the Mouse

Abstract

The muscular dystrophies caused by dy and dy2J on a C57BL/6J genetic background are similar in quality. At 1 month, slight differences occur in distribution of the muscle lesions, diffuse and focal, respectively, but at 3 months little, if any, differences exist. The dy dystrophy appears the same histologically on either the C57BL/6J or original 129/ReJ and 129B6F backgrounds.
