Variant summary

Our verdict is Pathogenic. The variant received 20 ACMG points: 20P and 0B. PS3 PM1 PM2 PM5 PP3_Moderate PP5_Very_Strong

The NM_007126.5(VCP):​c.463C>T​(p.Arg155Cys) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 13/22 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV000329986: Functional studies show that R155C causes loss of function in an in vitro culture model of frontotemporal lobar dementia (Gitcho et al., 2009) and studies using patient fibroblasts harboring the R155C variant show mitochondrial uncoupling resulting in reduced cellular ATP production (Bartolome et al., 2013)." and additional evidence is available in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R155P) has been classified as Likely 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

Our verdict: Pathogenic. The variant received 20 ACMG points.

• PS3: PS3 evidence extracted from ClinVar submissions: SCV000329986: Functional studies show that R155C causes loss of function in an in vitro culture model of frontotemporal lobar dementia (Gitcho et al., 2009) and studies using patient fibroblasts harboring the R155C variant show mitochondrial uncoupling resulting in reduced cellular ATP production (Bartolome et al., 2013).; SCV000813149: Experimental studies have shown that this missense change affects VCP function (PMID: 16984901, 23056506, 27768726, 28360103).
• PM1: In a hotspot region, there are 10 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 11 uncertain in NM_007126.5
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr9-35065363-C-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 8472.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.913
• PP5: Variant 9-35065364-G-A is Pathogenic according to our data. Variant chr9-35065364-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 8469.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
