Variant summary

Our verdict is Likely pathogenic. Variant got 7 ACMG points: 7P and 0B. PM2 PM5 PP2 PP3_Moderate

The NM_007126.5(VCP):​c.1160A>C​(p.Asn387Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N387H) has been classified as Pathogenic.

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.

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr9-35061612-T-G is described in Lovd as [Pathogenic].
• PP2: Missense variant in the VCP gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 36 curated pathogenic missense variants (we use a threshold of 10). The gene has 19 curated benign missense variants. Gene score misZ: 5.4064 (above the threshold of 3.09). Trascript score misZ: 8.1614 (above the threshold of 3.09). GenCC associations: The gene is linked to 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, 0.881
