These mice have a very mild phenotype with minimal histological appearance of the disease in skeletal muscles. These mice show reduced body weight, mild deficits in forelimb strength and motor coordination around 3 months age. Evidence of atrophy, fiber area variability, necrosis and regeneration typical of LGMD2A biopsies are seen in this model. C57BL/6 mice are the wild-type controls for this model.
