Aging-associated genes and let-7 microRNAs: a contribution to myogenic program dysregulation in oculopharyngeal muscular dystrophy

2019

Oculopharyngeal muscular dystrophy (OPMD) is a late-onset muscle disease caused by an abnormal (GCN) triplet expansion within the polyadenylate-binding protein nuclear 1 gene and consequent mRNA pr...

Oculopharyngeal muscular dystrophy in a northern German family linked to chromosome 14q, and presenting carnitine deficiency

1997

We report the evaluation of oculopharyngeal muscular dystrophy (OPMD) in a large northern German family, which can be traced back six generations and is unrelated to French-Canadian families. The symptoms in this family start at about 50 years of age and include dysphagia, bilateral ptosis, and in some cases a slowly progressive atrophy and weakness of other extraocular, facial or limb girdle muscles. The muscle biopsies showed the pathognomonic ultrastructural finding of characteristic intranuclear filaments. Linkage analysis confirmed that this family is also linked to chromosome 14q markers. Haplotype analysis revealed that a unique haplotype segregates with the disease which is differen…

Value of insoluble PABPN1 accumulation in the diagnosis of oculopharyngeal muscular dystrophy.

2019

Background and purpose The aim was to assess the value of insoluble PABPN1 muscle fibre nuclei accumulation in the diagnosis of atypical cases of oculopharyngeal muscular dystrophy (OPMD). Methods Muscle biopsies from a selected cohort of 423 adult patients from several Italian neuromuscular centres were analysed by immunofluorescence: 30 muscle biopsies of genetically proven OPMD, 30 biopsies from patients not affected by neuromuscular disorders, 220 from genetically undiagnosed patients presenting ptosis or swallowing disturbances, progressive lower proximal weakness and/or isolated rimmed vacuoles at muscle biopsy and 143 muscle biopsies of patients affected by other neuromuscular diseas…
