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).
