Abstract:
INTRODUCTION:Valosin-containing protein (VCP) variants that affect muscle, bone, and the nervous system are termed multisystem proteinopathy. VCP myopathy is manifested as limb-girdle weakness, distal weakness and scapuloperoneal weakness. METHODS:We reviewed clinical, genetic, and muscle biopsy data from 6 members of a family with VCP myopathy. RESULTS:Clinical features of family members were complex and included dementia, myopathy, and hearing impairment. Ophthalmoplegia, ptosis, and dysphagia were present in 3 siblings. Rimmed vacuoles were observed in muscle biopsies, consistent with the pathological changes of VCP myopathy. A heterozygous VCP c.463C>A (p.R155S) that segregated in an autosomal-dominant pattern was identified by genetic analysis. CONCLUSIONS:VCP myopathy can cause unusual manifestations that include ophthalmoplegia, ptosis, and dysphagia. This study increased our understanding of the clinical manifestations of VCP myopathy.
