Limb-girdle muscular dystrophy is a term for a group of diseases that cause weakness and wasting of the muscles in the arms and legs. The muscles most affected are those closest to the body (proximal muscles), specifically the muscles of the shoulders, upper arms, pelvic area, and thighs Pathogenic mutations in the gene encoding the giant skeletal muscle protein titin (TTN) are associated with several muscle disorders, including cardiomyopathy, recessive congenital myopathies and limb-girdle muscular dystrophy (LGMD) type10 The TTN gene provides instructions for making a very large protein called titin. This protein plays an important role in muscles the body uses for movement (skeletal muscles) and in heart (cardiac) muscle. Slightly different versions (called isoforms) of titin are made in different muscles
Limb-girdle muscular dystrophy is a group of disorders which affect the voluntary muscles around the hips and shoulders. The conditions are progressive, leading to a loss of muscle strength and bulk over a number of years. Onset may occur in childhood, adolescence, young adulthood, or even later Limb-girdle muscular dystrophy (LGMD) is a diverse group of disorders with many subtypes categorized by disease gene and inheritance. LGMD usually manifests in the proximal muscles around the hips and shoulders Phenotypes for gene: TTN were changed from Muscular dystrophy, limb-girdle, type 2J 608807 to Muscular dystrophy, limb-girdle, type 2J, 608807; Limb girdle muscular dystrophy; Distal myopathy; Myofibrillar myopathy; Congenital myopathy; dilated cardiomyopath Limb-girdle muscular dystrophy 2J (LGMD2J) is caused by homozygous mutation in the titin gene (TTN). Heterozygous mutation in the titin gene causes tardive tibial muscular dystrophy (TMD). Mutation in the titin gene also causes dilated cardiomyopathy type 1G (CMD1G)

The diagnosis of muscular dystrophy was suggested by these results. The patient agreed to another muscle biopsy, and samples were taken from the left biceps and right vastus lateralis muscles. Ring fibers, increased centrally placed nuclei and lobulated fibers were observed, suggesting limb girdle muscular dystrophy (LGMD) In this group of disorders, the mortality ascribed to the disease and/or the complications thereof are negligible. However, the prognosis in limb-girdle muscular dystrophy with regard to mobility, self-care, and the maintenance of the ability to work is dependent on the aggressive, goal-directed management described in various subsections of this article The diagnosis of limb-girdle muscular dystrophy can be done via muscle biopsy, which will show the presence of muscular dystrophy, and genetic testing is used to determine which type of muscular dystrophy a patient has. Immunohistochemical dystrophin tests can indicate a decrease in dystrophin detected in sarcoglycanopathies.In terms of sarcoglycan deficiency there can be variance (if α.
Limb-girdle muscular dystrophies are a group of specific neuromuscular disorders that specifically affect the shoulders and pelvic joints.
