Patients with proximal (limb-girdle) weakness may have difficulty rising from a chair, climbing stairs, or lifting their arms overhead to perform activities of daily living (e.g., combing hair).2...
Adult-onset disease usually involves both shoulder and pelvic girdles with gradually increasing proximal limb (close to the body core) weakness. Facial weakness is usually mild or totally absent. Major clinical features of LGMDs are progressive weakness and muscle atrophy mainly involving the shoulder girdle (scapulohumeral type), the pelvic girdle (pelvifemoral type), or both.Estimated Reading Time: 4 mins
LGMDs are the prime examples of the limb girdle pattern, with slowly progressive proximal muscle involvement. The weakness usually begins in the lower limbs and progresses to upper limbs, typically over many months or years. Rarely, it begins in the upper limb girdle.Estimated Reading Time: 11 mins
The earliest descriptions of limb-girdle weakness are ascribed to Leyden [ 3] and Möbius [ 4] in 1876 and 1879, respectively. They described adult patients with a pelvic and femoral distribution of...
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.Estimated Reading Time: 10 mins
Collectively, these are called the limb girdles, and it is the observed weakness and atrophy (wasting) of the muscles connected to the limb girdles that has given this group of disorders its name. Together, the group of disorders that constitute LGMD is the fourth most common genetic cause of muscle weakness with an estimated prevalence in about 2 in every 100,000 individuals. 1,2,3

These diseases affect the voluntary muscles , which are the muscles that are moved on purpose, such as the arms, legs, fingers, toes, and facial muscles. The muscle weakness typically affects the muscles closest to the center of the body proximal muscles such as the upper legs. The disease is progressive, leading to a loss of muscle strength and bulk over a number of years. The disease is inherited in an autosomal dominant manner. A diagnosis of LGMD1B is suspected in people who have signs and symptoms consistent with the disease, and the diagnosis can be confirmed with laboratory tests. While there are not treatments that can reverse the muscle weakness associated with the disease, supportive treatment can decrease the complications.

Summary Summary. Symptoms Symptoms. The muscle weakness can cause an unusual walking gait and difficulty running or using the stairs. About half of all affected individuals show signs of the disease in childhood. Other symptoms of the disease may include difficulty straightening the elbows elbow contracture and heart problems including arrhythmia or left ventricular hypertrophy. Do you have updated information on this disease? We want to hear from you. Cause Cause. The LMNA gene provides instructions to the body to make a protein that is responsible for providing stability and strength to the cells. Specifically, LMNA provides instructions to make a protein that is located in the nuclear envelope , which surrounds the nucleus. The proteins of the nuclear envelope help move molecules in and out of the nucleus. When there are changes to the LMNA gene, this protein is not made correctly. It is not clear exactly why changes in this gene cause the signs and symptoms associated with LGMD1B, but it is thought that the protein created by the LMNA gene may be important for controlling the expression of other genes. Inheritance Inheritance. We inherit one copy of each gene from our mother and one from our father. This could happen for a couple of reasons.

Limb girdle muscular dystrophy LGMD is inherited. It is a disorder of voluntary muscles that results in progressive limb, shoulder, and hip girdle weakness and wasting. Some of the symptoms that show these types of weaknesses are soreness of the muscles and joints, walking with a waddle, difficulties standing from the sitting position, difficulties using the arms above the head, and in some, problems with the heart and breathing. Onset of symptoms may occur from childhood to adulthood and in either males or females. It has been thought that if the symptoms arise in adulthood, the progression is not as fast as if they arise in childhood. LGMD does not shorten one's lifespan, however, problems can arise if the heart and lungs become weak. What causes Limb Girdle Muscular Dystrophy? LGMD is caused by mutations of genes that result in abnormal function of proteins in muscles, thereby causing progressive muscle weakness. The inheritance pattern of LGMD varies and different genetic defects may result in the same clinical symptoms in different patients.
