dbSNP rs779959657: VCP:p.Arg93His (chr9-35067915-C-T) – ACMG Classification: Uncertain_significance (3 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 7P and 4B. PM1PM5PP3_ModeratePP5BS2

The NM_007126.5(VCP):c.278G>A(p.Arg93His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000682 in 1,614,076 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R93C) 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

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 3 ACMG points.

PM1

In a hotspot region, there are 13 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 6 uncertain in NM_007126.5

PM5

Other missense variant is known to change same aminoacid residue: Variant chr9-35067916-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 593071.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.867

PP5

Variant 9-35067915-C-T is Pathogenic according to our data. Variant chr9-35067915-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 449554.

BS2

High AC in GnomAdExome4 at 10 AD gene.
