A novel mutation in the VCP gene (G157R) in a German family with inclusion-body myopathy with Paget disease of bone and frontotemporal dementia

Muscle Nerve. 2009 Mar;39(3):389-91. doi: 10.1002/mus.21225.

Abstract

Mutations in the valosin-containing protein (VCP) are known to cause autosomal-dominant inclusion-body myopathy with Paget's disease of bone and frontotemporal dementia (IBMPFD). We report a novel missense mutation (G157R) in the N-terminal region of the VCP gene in a German family. Family members presented with mild to moderate proximal muscle weakness, Paget disease of bone, and signs of early cognitive decline, with onset in the fourth decade. Two family members also showed signs of early hearing impairment, which was confirmed to be sensorineural in one person, a symptom not yet described in the context of IBMPFD.
