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.475C>T(p.Arg159Cys) variant causes a missense change. The variant allele was found at a frequency of 0.00000137 in 1,461,874 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. R159S) has been classified as Pathogenic.

Published functional studies demonstrate that the R159C mutant protein results in substrate accumulation and reduced endoplasmic reticulum associated degradation (Erzurumlu et al., 2013).; Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Reported previously in several individuals with inclusion body myopathy with Paget's disease of bone and frontotemporal demantia (IBMPFD) (Spina et al., 2013; Bersano et al., 2009).; This variant is associated with the following publications: (PMID: 22572540, 21816654, 22991237, 23333620, 17889967, 22900631, 27594680, 28542158, 30279455, 28692196) -

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 159 of the VCP protein (p.Arg159Cys). This variant is present in population databases (rs387906789, gnomAD 0.0009%). This missense change has been observed in individuals with clinical features of VCP-related conditions (PMID: 17889967, 21816654, 23152587, 28692196). ClinVar contains an entry for this variant (Variation ID: 280123). 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: 23333620). This variant disrupts the p.Arg159 amino acid residue in VCP. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 16247064, 19704082, 22270372, 24829604, 25492614, 26555887, 27226613). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
