Summaries for Muscular Dystrophy, Limb-Girdle, Type 2b

NIH Rare Diseases : 50 limb-girdle muscular dystrophy, type 2b (lgmd2b) is one of many forms of limb-girdle muscular dystrophy, a group of disorders that affect the voluntary muscles of the hips and shoulders. lgmd2b is characterized by early weakness and wasting (atrophy) of the pelvic and shoulder girdle muscles in adolescence or young adulthood. the age of onset typically ranges from 15 to 35 years, and legs are usually affected first. symptoms include the inability to tiptoe and difficulty walking and running. cardiac (heart) and respiratory involvement is uncommon. it is usually slowly progressive, with need of a wheelchair 10 to 20 years after onset. lgmd2b is caused by mutations in the dysf gene and is inherited in an autosomal recessive manner. there is no specific treatment. management is tailored to each person and may include physical therapy and stretching exercises; use of aids for mobility; and surgery as needed for orthopedic complications. last updated: 3/21/2016

MalaCards based summary : Muscular Dystrophy, Limb-Girdle, Type 2b, also known as lgmd2b, is related to autosomal recessive limb-girdle muscular dystrophy type 2b and dysferlinopathy, and has symptoms including muscular dystrophy, difficulty climbing stairs and increased connective tissue. An important gene associated with Muscular Dystrophy, Limb-Girdle, Type 2b is DYSF (Dysferlin). The drugs Deflazacort and Anti-Inflammatory Agents have been mentioned in the context of this disorder. Affiliated tissues include heart and skeletal muscle.

UniProtKB/Swiss-Prot : 71 Limb-girdle muscular dystrophy 2B: An autosomal recessive degenerative myopathy characterized by weakness and atrophy starting in the proximal pelvifemoral muscles, with onset in the late teens or later, massive elevation of serum creatine kinase levels and slow progression. Scapular muscle involvement is minor and not present at onset. Upper limb girdle involvement follows some years after the onset in lower limbs.
