LGMD1C (also known as caveolinopathy) is an autosomal dominant form of limb girdle muscular dystrophy (LGMD). The age of onset of muscle weakness is variable and ranges from childhood to adulthood.
LGMD1C is a rare disease and not many families affected by this muscular dystrophy have been reported. Because of this, the range of weakness and the progression of the condition of people with caveolin 3 deficiency are not well known.
Life expectancy is generally within a normal range because the heart and breathing muscles are usually not affected.
