ullrich congenital muscular dystrophy
objective ullrich congenital muscular dystrophy is a rather severe type of congenital muscular dystrophy with early onset features related to motor development. in general it is inherited in autosomal recessive principles, however in the western world mostly seen with de novo dominant mutations in the collagen vi genes. milder form of the condition is the bethlem myopathy. there may be overlap ...
متن کاملModerately progressive Ullrich congenital muscular dystrophy.
OBJECTIVES To describe genetic and clinical features of Ullrich congenital muscular dystrophy (UCMD), and to report the case of a patient diagnosed with UCMD after an exhaustive investigation, which included collagen VI immunohistochemical and genomic analyses. DESCRIPTION This study was based on clinical, immunohistochemical assessment of muscle tissue and genomic analysis of dermal fibrobla...
متن کاملUllrich scleroatonic muscular dystrophy is caused by recessive mutations in collagen type VI.
Ullrich syndrome is a recessive congenital muscular dystrophy affecting connective tissue and muscle. The molecular basis is unknown. Reverse transcription-PCR amplification performed on RNA extracted from fibroblasts or muscle of three Ullrich patients followed by heteroduplex analysis displayed heteroduplexes in one of the three genes coding for collagen type VI (COL6). In patient A, we detec...
متن کاملTendon Extracellular Matrix Alterations in Ullrich Congenital Muscular Dystrophy
Collagen VI (COLVI) is a non-fibrillar collagen expressed in skeletal muscle and most connective tissues. Mutations in COLVI genes cause two major clinical forms, Bethlem myopathy and Ullrich congenital muscular dystrophy (UCMD). In addition to congenital muscle weakness, patients affected by COLVI myopathies show axial and proximal joint contractures and distal joint hypermobility, which sugge...
متن کاملCyclosporine A in Ullrich Congenital Muscular Dystrophy: Long-Term Results
Six individuals with Ullrich congenital muscular dystrophy (UCMD) and mutations in the genes-encoding collagen VI, aging 5-9, received 3-5 mg/kg of cyclosporine A (CsA) daily for 1 to 3.2 years. The primary outcome measure was the muscle strength evaluated with a myometer and expressed as megalimbs. The megalimbs score showed significant improvement (P = 0.01) in 5 of the 6 patients. Motor func...
