Ullrich Congenital Muscular Dystrophy Possibly Related With COL6A1 p.Gly302Arg Variant
Ullrich congenital muscular dystrophy (UCMD) is characterized by congenital weakness, proximal joint contractures, and hyperlaxity of distal joints. UCMD is basically due to a defect in extra cellular matrix protein, collagen type VI. A 37-year-old woman who cannot walk independently visited our outpatient clinic. She had orthopedic deformities (scoliosis, joint contractures, and distal joint h...
متن کاملTeaching NeuroImages: characteristic phenotype of Ullrich congenital muscular dystrophy.
A 21-year-old woman presented with clinically classic signs of Ullrich congenital muscular dystrophy (figure). Genetic testing of collagen VI genes revealed a homozygous mutation c.2329T.C, p.Cys777Arg in the COL6A2 gene, consistent with the clinical diagnosis. Collagen type VI–related disorders represent a spectrum of overlapping phenotypes: Bethlem myopathy at the milder end, and Ullrich cong...
متن کاملullrich 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 کاملMutations in COL6A3 cause severe and mild phenotypes of Ullrich congenital muscular dystrophy.
Ullrich congenital muscular dystrophy (UCMD) is an autosomal recessive disorder characterized by generalized muscular weakness, contractures of multiple joints, and distal hyperextensibility. Homozygous and compound heterozygous mutations of COL6A2 on chromosome 21q22 have recently been shown to cause UCMD. We performed a genomewide screening with microsatellite markers in a consanguineous fami...

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...
