Is VCP p.Val28Ile (c.82G>A) pathogenic?

VCP p.Val28Ile (c.82G>A) is classified Uncertain significance in VCP (ClinVar, Single submitter, 1 submitter; last evaluated 2022-10-24). AlphaMissense: likely benign (0.3147); Absent from gnomAD v4.1; Associated with inclusion body myopathy with Paget disease of bone and frontotemporal dementia.

How common is VCP p.Val28Ile (c.82G>A) in the general population?

VCP p.Val28Ile (c.82G>A) is absent from gnomAD v4.1 (gnomAD).

What do computational predictors say about VCP p.Val28Ile (c.82G>A)?

AlphaMissense predicts likely benign (score 0.3147) — an in-silico prediction, not a clinical call.

VCP p.Val28Ile

Q: What condition is associated with VCP p.Val28Ile (c.82G>A)?

VCP p.Val28Ile (c.82G>A) is associated with inclusion body myopathy with Paget disease of bone and frontotemporal dementia, frontotemporal dementia and/or amyotrophic lateral sclerosis 6 (ClinVar).

Q: How is Inclusion body myopathy with Paget disease of bone and frontotemporal dementia inherited?

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