About

The objective of the study is to answer the following important questions. Deficiency of the dysferlin protein is the cause of a very rare limb-girdle muscular dystrophy (LGMD-2B) that leads to significant disability. This disease is caused by mutations in the dysferlin gene. It is a recessive inherited disease, meaning that both copies of the gene must have mutations for the disease to develop. This study aims to analyze the frequency of carriers of a mutation in the DYSF gene in the Caucasian population. To achieve this, The investigator analyzed the blood of 100 healthy volunteers from their local area, quantifying the dysferlin protein in peripheral blood monocytes.
