Is VCP p.Asp428Val (c.1283A>T) pathogenic?

VCP p.Asp428Val (c.1283A>T) is classified Uncertain significance in VCP (ClinVar, Single submitter, 1 submitter; last evaluated 2021-12-02). AlphaMissense: likely pathogenic (0.8495); Absent from gnomAD v4.1; Associated with frontotemporal dementia and/or amyotrophic lateral sclerosis 6.

What condition is associated with VCP p.Asp428Val (c.1283A>T)?

VCP p.Asp428Val (c.1283A>T) is associated with frontotemporal dementia and/or amyotrophic lateral sclerosis 6, inclusion body myopathy with Paget disease of bone and frontotemporal dementia (ClinVar).

How common is VCP p.Asp428Val (c.1283A>T) in the general population?

VCP p.Asp428Val (c.1283A>T) is absent from gnomAD v4.1 (gnomAD).

What do computational predictors say about VCP p.Asp428Val (c.1283A>T)?

AlphaMissense predicts likely pathogenic (score 0.8495) — an in-silico prediction, not a clinical call.

VCP p.Asp428Val

Q: How is Frontotemporal dementia with motor neuron disease inherited?

Typically Autosomal dominant (Orphanet). A genetic counselor can assess individual risk for a family.

ClinVar classifies this uncertain; the computational predictors unanimously lean damaging — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.
