VCP and amyotrophic lateral sclerosis: Our system review showed that ALS patients with some VCP mutations (p.R93C, p.D98V, p.I114V, p.R155C, p.R155H, p.R159C, p.R191G, and p.R191Q) had a relatively slow progression and survival of more than 10 years (Table 3), which is consistent with the phenotype of our patients.
