Distal myopathy refers to a heterogeneous group of disorders in which the initial manifestations are weakness and atrophy of the hands and feet. We report a family segregating an autosomal dominant distal myopathy, with multiple affected individuals in whom vocal cord and pharyngeal weakness may
Myotilin (MYOT) is a promising candidate gene for Vocal Cord and Pharyngeal Weakness with Distal Myopathy (VCPDM, also known as MPD2). Located within the minimum VCPDM candidate interval, myotilin mutations also cause a similarly progressive and adult-onset muscle disease. We examined myotilin in
Distal myopathy with rimmed vacuoles (DMRV) and hereditary inclusion body myopathy (hIBM) share similar clinical features, including onset in young adulthood with preferential involvement of the anterior compartment of the lower legs and sparing of the quadriceps femoris muscles. The most
The aim of our study was to describe patients with the p.D12Y variant (previously reported as D11Y) in SOD1 disclosing heterogeneous clinicopathological features.We performed clinical, electrophysiological, MRI and muscle pathology studies in four SOD1 Two-dimensional echocardiography, cardiac catheterization, electrophysiologic studies, and biopsies of cardiac and skeletal muscle were performed in a patient with complete atrioventricular block as the initial manifestation of restrictive cardiomyopathy. The patient also showed distal myopathy with
Distal myopathy with rimmed vacuoles (DMRV), also called hereditary inclusion body myopathy (hIBM), is characterized clinically by weakness and atrophy that initially involves the distal muscles and pathologically by the presence of rimmed vacuoles (RVs) or intracellular protein deposits in
Distal myopathy with rimmed vacuoles or GNE myopathy, is an early adult-onset myopathy with slow progression that preferentially affects the tibialis anterior muscle. Severely affected patients show marked limb muscle atrophy together with respiratory dysfunction. The disease is caused by a mutation
We investigated a four-generation family of German ancestry with distal myopathy. Four individuals in two generations were affected. Foot and toe extensor paresis progressing very slowly over decades was the core neurological sign, reflected by fatty infiltration of the lower leg extensor muscles on
OBJECTIVE
To determine the phenotype variability associated with the specific C-terminal M-line titin mutation known to cause autosomal dominant distal myopathy, tibial muscular dystrophy (TMD; MIM 600334), and limb girdle muscular dystrophy 2J (LGMD2J).
METHODS
Three hundred eighty-six individuals
Two female patients with distal muscular dystrophy (Miyoshi) are reported. Neurological examination revealed marked weakness and a low skin temperature of both lower legs, especially over the gastrocnemius muscle. Biopsy specimens of the anterior tibial muscle exhibited myopathological features
Miyoshi-type distal muscular dystrophy has now been found to be more frequent outside Japan than was previously thought. We studied 24 Dutch patients with Miyoshi-type distal muscular dystrophy and focused on its clinical expression and natural history, muscle CT-scans and muscle biopsy findings.
Miyoshi myopathy is the most common form of recessive distal myopathy. Recessive mutations in the ANO5 gene have been recently identified in Northern Europe as a cause of non dysferlin-linked distal myopathy and limb girdle muscular dystrophy. We report here the first French cases of anoctamin 5
Welander distal myopathy is a rare autosomal dominant disorder characterized by muscle weakness in the hands and feet. Exome sequencing of affected families discovered a segregating p.Glu384Lys pathogenic variant in TIA-1 as the main genetic cause of Welander distal myopathy. TIA-1 encodes an
Distal myopathy with rimmed vacuoles (DMRV) or hereditary inclusion body myopathy (hIBM) is an adult onset slowly progressive myopathy secondary to mutations in the UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase (GNE) gene that encodes a bifunctional enzyme which catalyzes the
