CALPAIN 3

Calpain, a heterodimer consisting of a large and a small subunit, is a major intracellular protease, although its function has not been well established. This gene encodes a muscle-specific member of the calpain large subunit family that specifically binds to titin. Mutations in this gene are associated with limb-girdle muscular dystrophies type 2A. Alternate promoters and alternative splicing result in multiple transcript variants encoding different isoforms and some variants are ubiquitously expressed. [provided by RefSeq, Jul 2008]

Muscular dystrophy, limb-girdle, autosomal recessive 1 (LGMDR1): An autosomal recessive degenerative myopathy characterized by progressive symmetrical atrophy and weakness of the proximal limb muscles and elevated serum creatine kinase. The symptoms usually begin during the first two decades of life, and the disease gradually worsens, often resulting in loss of walking ability 10 or 20 years after onset.
Muscular dystrophy, limb-girdle, autosomal dominant 4 (LGMDD4): A form of autosomal dominant limb-girdle muscular dystrophy, a myopathy characterized by proximal and/or distal muscle weakness and atrophy. The age at onset is variable and can range from the first to the sixth decade, although later onset is less common. LGMDD4 is characterized by onset of proximal muscle weakness in young adulthood, gait difficulties, increased serum creatine kinase, myalgia, and back pain. Some patients may have upper limb involvement. Disease severity and expressivity are highly variable.
