Abstract
The phenotype in limb-girdle muscular dystrophy (LGMD) type 21 was defined by mutation analysis, protein studies, and respiratory and cardiac involvement studied in 16 patients from 14 families with fukutin-related protein (FKRP) gene mutations and LGMD, at the Institute of Human Genetics, University Newcastle upon Tyne, UK.
Highlights
Two unrelated patients with novel homozygous missense mutations (L86P and A92T) in caveolin-3 gene (CAV3), presenting with a severe form of rippling muscle disease (RMD), are reported from the University of Bonn, and other centers in Germany

Thirteen adults were homozygous for the common C826A mutation in FKRP
Summary
Two unrelated patients with novel homozygous missense mutations (L86P and A92T) in caveolin-3 gene (CAV3), presenting with a severe form of rippling muscle disease (RMD), are reported from the University of Bonn, and other centers in Germany. The phenotype in limb-girdle muscular dystrophy (LGMD) type 21 was defined by mutation analysis, protein studies, and respiratory and cardiac involvement studied in 16 patients from 14 families with fukutin-related protein (FKRP) gene mutations and LGMD, at the Institute of Human Genetics, University Newcastle upon Tyne, UK. Five patients had symptoms in childhood, including a peculiar gait, inability to run, muscle cramps, and myalgia. The remaining 11 patients had onset of symptoms in the 2nd to 4th decades.
