Abstract
The authors report a 71-year-old woman with limb-girdle muscular dystrophy (LGMD) associated with an R27Q mutation in the CAV3 gene. Immunohistochemistry showed a >90% reduction of caveolin-3 on the sarcolemma by western blot, and anti-dysferlin immunoreactivity was reduced. This case emphasizes that an R27Q missense mutation in the CAV3 gene can lead to various clinical phenotypes including hyperCKemia, rippling muscle disease, distal myopathy, and LGMD1C.
