Genes affected

VCP (HGNC:12666): (valosin containing protein) This gene encodes a member of the AAA ATPase family of proteins. The encoded protein plays a role in protein degradation, intracellular membrane fusion, DNA repair and replication, regulation of the cell cycle, and activation of the NF-kappa B pathway. This protein forms a homohexameric complex that interacts with a variety of cofactors and extracts ubiquitinated proteins from lipid membranes or protein complexes. Mutations in this gene cause IBMPFD (inclusion body myopathy with paget disease of bone and frontotemporal dementia), ALS (amyotrophic lateral sclerosis) and Charcot-Marie-Tooth disease in human patients.

VCP (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), VCP. . Gene score misZ 5.4064 (greater than the threshold 3.09). Trascript score misZ 8.1614 (greater than threshold 3.09). GenCC has associacion of gene with spastic paraplegia-Paget disease of bone syndrome, adult-onset distal myopathy due to VCP mutation, frontotemporal dementia and/or amyotrophic lateral sclerosis 6, Charcot-Marie-Tooth disease type 2Y, amyotrophic lateral sclerosis, inclusion body myopathy with Paget disease of bone and frontotemporal dementia, frontotemporal dementia with motor neuron disease, inclusion body myopathy with Paget disease of bone and frontotemporal dementia type 1.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.897
