Summaries for Bethlem Myopathy 1

About this section
NIH Rare Diseases:46 Bethlem myopathy is an inherited movement disorder characterized by progressive muscle weakness and joint stiffness (contractures) in the fingers, wrists, elbows, and ankles. due to a progressive course, up to two-thirds of people with this condition require a walker or wheelchair after the age of 50. bethlem myopathy is caused by mutations in the col6a1, col6a2, and col6a3 genes. most cases are inherited in an autosomal dominant pattern and occur as the result of a new mutation. in rare cases, the disease follows an autosomal recessive pattern of inheritance. treatment depends upon individual symptoms, but routinely involves physical therapy. surgery or other measures may be undertaken as needed. last updated: 2/4/2015

MalaCards based summary: Bethlem Myopathy 1, also known as bethlem myopathy, is related to ullrich congenital muscular dystrophy 1 and bethlem myopathy 2, and has symptoms including limitation of joint mobility, myopathy and emg abnormality. An important gene associated with Bethlem Myopathy 1 is COL6A2 (Collagen Type VI Alpha 2 Chain), and among its related pathways are NCAM1 interactions and PI3K-Akt signaling pathway. Related mouse phenotypes are skeleton and growth/size/body region.

UniProtKB/Swiss-Prot:68 Bethlem myopathy 1: A benign proximal myopathy characterized by early childhood onset and joint contractures most frequently affecting the elbows and ankles.
