Variant summary
Our verdict is Pathogenic. The variant received 16 ACMG points: 16P and 0B. PM1PM2PM5PP3_ModeratePP5_Very_Strong
The NM_007126.5(VCP):c.572G>A(p.Arg191Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,866 control chromosomes in the GnomAD database, with no homozygous occurrence. 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 (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R191P) has been classified as Likely pathogenic.

Submissions by phenotype
not provided Pathogenic:6
- -
The frequency of this variant in the general population is consistent with pathogenicity. Found in at least one patient with expected phenotype for this gene. Predicted to have a damaging effect on the protein. Assessment of experimental evidence suggests this variant results in abnormal protein function. -
Published In vitro studies of R191Q expression support a damaging effect on protein function (Gitcho et al., 2009; Ludtmann et al., 2017); Not observed at a significant frequency in large population cohorts (Lek et al., 2016); This variant is associated with the following publications: (PMID: 29789581, 28364293, 27708273, 21145000, 15034582, 21984748, 19364651, 28564594, 28360103, 27226613, 23498975, 22270372, 24196964, 19237541, 23333620, 22900631, 30279455) -

Inclusion body myopathy with Paget disease of bone and frontotemporal dementia;C5436279:Frontotemporal dementia and/or amyotrophic lateral sclerosis 6 Pathogenic:1
This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 191 of the VCP protein (p.Arg191Gln). This variant is present in population databases (rs121909334, gnomAD 0.004%). This missense change has been observed in individuals with inclusion body myopathy with Paget’s disease of the bone and frontotemporal dementia (IBMPFD), facioscapulohumeral muscular dystrophy-like phenotype and amyotrophic lateral sclerosis (PMID: 15034582, 21145000, 21984748, 22900631). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 8473). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt VCP protein function with a negative predictive value of 80%. Experimental studies have shown that this missense change affects VCP function (PMID: 19237541, 22270372, 23333620, 23498975, 24196964, 27226613). For these reasons, this variant has been classified as Pathogenic. -
