A 32-year-old woman and a 50-year-old man with clinically typical Bethlem myopathy developed seemingly spontaneous keloids on their shoulder region (figure). The patients did not recall any significant trauma to the skin of this region. Bethlem myopathy (MIM #158810) is caused by dominant and recessive mutations in the collagen VI genes: COL6A1, COL6A2, and COL6A3. Skin manifestations include h...

Myocardial infarction (MI) is a heart disease with high morbidity and mortality rates, thus it is critical to identify genes that serve roles during its pathogenesis. The objective of the present study was to identify potentially relevant genes during the progression of the disease. Blood samples from patients with MI and normal controls (n=3/group) were obtained, the RNA was extracted and cDNA...

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...

The collagen type VI-related disorders are nowadays considered to be a continuum of overlapping phenotypes with Bethlem myopathy at the mild end and Ullrich congenital muscular dystrophy (UCMD) at the severe end. In between these phenotypes there are collagen type VI-related limb-girdle muscular dystrophy and myosclerosis myopathy. Most cases of Bethlem myopathy have autosomal dominant inherita...

Mutations in the genes encoding collagen VI (COL6A1, COL6A2, and COL6A3) cause Bethlem myopathy (BM) and Ullrich congenital muscular dystrophy (UCMD), two conditions which were previously believed to be completely separate entities. BM is a relatively mild dominantly inherited disorder characterised by proximal weakness and distal joint contractures. UCMD was originally described as an autosoma...

Mutations in COL6A1, COL6A2 and COL6A3 genes result in collagen VI myopathies: Ullrich congenital muscular dystrophy (UCMD), Bethlem myopathy (BM) and intermediate phenotypes. At present, none of the existing diagnostic techniques for evaluating collagen VI expression is quantitative, and the detection of subtle changes in collagen VI expression remains challenging. We investigated flow cytomet...

Synonyms Spectrum of phenotypes: Mild: Bethlem myopathy/ benign congenital muscular dystrophy Intermediate: Limb-girdle muscular dystrophy; myosclerosis myopathy Severe: Ullrich myopathy/ congenital atonic sclerotic muscular dystrophy First described by Ullrich in 1930 and Bethlem in 1976 respectively [1]. Caused by mutations in any of the 3 genes which code for collagen type VI synthesis, COL6...

Respiratory muscle testing is often limited to noninvasive volitional tests such as vital capacity and maximal static pressures. We report the case of a 12-year-old boy with congenital muscular dystrophy (CMD) in whom invasive and non-volitional respiratory muscle tests showed an elective diaphragmatic dysfunction with the preservation of expiratory muscle strength. This finding, coupled with a...
