How many types of limb-girdle muscular dystrophy are there?

Limb-girdle muscular dystrophies include at least 18 different inherited diseases. (There are 16 known genetic forms.) These disorders first affect the muscles around the shoulder girdle and hips.

What is limb-girdle pattern?

Limb–girdle muscular dystrophy (LGMD) is a genetically heterogeneous group of rare muscular dystrophies that share a set of clinical characteristics. It is characterised by progressive muscle wasting which affects predominantly hip and shoulder muscles. LGMD usually has an autosomal pattern of inheritance.

What are limb-girdle muscular dystrophies LGMD )?

Limb-girdle muscular dystrophies (LGMD) are a group of rare progressive genetic disorders that are characterized by wasting (atrophy) and weakness of the voluntary muscles of the hip and shoulder areas (limb-girdle area). Muscle weakness and atrophy are progressive and may spread to affect other muscles of the body.

What is limb-girdle muscular dystrophy type 2E?

Limb-girdle muscular dystrophy, type 2E is an autosomal recessive, pan-ethnic disorder that is caused by pathogenic variants in the gene SGCB. This form of muscular dystrophy presents with weakness of the pelvic and shoulder girdle in childhood, with symptoms usually present by the age of 12 years.
