The minimum prevalence of<unk> , as a group, likely ranges from 2.27-10 per 100,000 (1:44,000 to 1:10,000). LGMD is the fourth most common muscular dystrophy, after the dystrophinopathies, myotonic dystrophies, and facioscapulohumeral muscular dystrophy. The prevalence of individual LGMDs, as studied in the United States, in descending order, are those due to mutation of 1) calpain, 2) dysferlin, 3) collagen VI, 4) sarcoglycans, 5) anoctamin 5, and 6) fukutin-related protein. It is difficult to calculate the worldwide prevalence of even the most common LGMD types, due to the founder effect causing varying prevalence by region. The less common types are very rare, often only described is limited regions of the world.
