Seventy four patients with clinical presentation of LGMD and probably autosomal-recessive type of inheritance were examined. Five different mutations of FKRP gene responsible for LGMD2 type I were detected in eight (10.8%) patients. Two of them с.341C>G, c.826C>A were described before and three c.229C>T, с.265C>T, с.1078G>C were found for the first time. The significant clinical polymorphism due to the difference in age of manifestation and severity of clinical presentation was identified.
