Molecular Genetic Diagnosis of a Bethlem Myopathy Family with an Autosomal-Dominant COL6A1 Mutation, as Evidenced by Exome Sequencing
BACKGROUND We describe herein the application of whole exome sequencing (WES) for the molecular genetic diagnosis of a large Korean family with dominantly inherited myopathy. CASE REPORT The affected individuals presented with slowly progressive proximal weakness and ankle contracture. They were initially diagnosed with limb-girdle muscular dystrophy (LGMD) based on clinical and pathologic fe...
متن کاملBethlem myopathy in a Taiwanese family.
We report three cases of Bethlem myopathy from three consecutive generations of a Taiwanese family, including one woman aged 70, one man aged 40, and a boy aged 8. The clinical features of the patients included autosomal dominant inheritance, childhood or adolescent onset, mainly proximal and extensor involvement, early diffuse joint contractures, and absence of cardiac involvement. These featu...
متن کاملGenetic localization of Bethlem myopathy.
Bethlem myopathy is a rare autosomal dominant myopathy characterized by slowly progressive limb-girdle muscular atrophy and weakness, and contractures of multiple joints. To identify the genetic localization we used highly polymorphic microsatellite markers in a genome-wide search in six Dutch families. After excluding genetic linkage with 52 markers distributed evenly over the autosomes, signi...
متن کاملDominant collagen VI mutations are a common cause of Ullrich congenital muscular dystrophy.
Mutations in the three collagen VI genes COL6A1, COL6A2 and COL6A3 cause Bethlem myopathy and Ullrich congenital muscular dystrophy (UCMD). UCMD, a severe disorder characterized by congenital muscle weakness, proximal joint contractures and marked distal joint hyperextensibility, has been considered a recessive condition, and homozygous or compound heterozygous mutations have been defined in CO...

To cite: Morrow JM, Pitceathly RDS, Quinlivan RM, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013008596 DESCRIPTION A 44-year-old man presented with progressive limb girdle weakness from 10 years of age. The inheritance pattern was autosomal dominant; two siblings, his mother and maternal grandfather were similarly affected. On examination there was an...
