VCP mutations were first associated with inclusion body myopathy with Paget's disease of bone and frontotemporal dementia (IBMPFD) but was later associated with amyotrophic lateral sclerosis and Charcot-Marie-Tooth disease. Now, a new name, "multisystem proteinopathy (MSP)", is proposed for this condition. VCP encodes valosin-containing protein, which is involved in protein degradation in the ubiquitin proteasome system. We report here two MSP patients with two novel heterozygous missense variants in VCP: c.259G>T (p.Val87Phe) and c.376A>G (p.Ile126Val).
