Sporadic inclusion body myositis (sIBM) has clinical, pathologic and pathomechanistic overlap with some inherited muscle and neurodegenerative disorders. In this study, DNA from 79 patients with sIBM was collected and the sequencing of 38 genes associated with hereditary inclusion body myopathy (IBM), myofibrillar myopathy, Emery-Dreifuss muscular dystrophy, distal myopathy, amyotrophic lateral sclerosis and dementia along with C9orf72 hexanucleotide repeat analysis was performed. No C9orf72 repeat expansions were identified, but; 27 rare (minor allele frequency <1%) missense coding variants in several other genes were identified. One patient carried a p.R95C missense mutation in VCP and another carried a previously reported p.I27V missense mutation in VCP. Mutations in VCP cause IBM associated with Paget's disease of the bone (PDB) and fronto-temporal dementia (IBMPFD). Neither patient had a family history of weakness or manifested other symptoms reported with VCP mutations such as PDB or dementia. In vitro analysis of these VCP variants found that they both disrupted autophagy similar to other pathogenic mutations. Although no clear genetic etiology has been implicated in sIBM pathogenesis, our study suggests that genetic evaluation in sIBM may be clinically meaningful and lend insight into its pathomechanism.

Based on approximately eight years of data collection with the nationwide Computer Registry of All Myopathies and Polyneuropathies (CRAMP) in the Netherlands, recent epidemiologic information for thirty neuromuscular disorders is presented. This overview includes age and gender data for a number of neuromuscular disorders that are either relatively frequently seen in the neuromuscular clinic, or have a particular phenotype. Since 2004, over 20,000 individuals with a neuromuscular disorder were registered in CRAMP; 56% men and 44% women. The number per diagnosis varied from nine persons with Emery-Dreifuss muscular dystrophy to 2057 persons with amyotrophic lateral sclerosis. Proportions of men ranged from 38% with post-polio syndrome to 68% with progressive spinal muscular atrophy, excluding X-chromosome linked disorders. Inclusion body myositis showed the highest median age at diagnosis of 70 years. These data may be helpful in the diagnostic process in clinical practice and trial readiness.
