Is VGF p.Arg428Pro (c.1283G>C) pathogenic?

VGF p.Arg428Pro (c.1283G>C) is classified Uncertain significance in VGF (ClinVar, Single submitter, 1 submitter; last evaluated 2022-07-20). AlphaMissense: likely benign (0.2385); Very rare (popmax 0.00685%, nfe).

How common is VGF p.Arg428Pro (c.1283G>C) in the general population?

VGF p.Arg428Pro (c.1283G>C) is very rare (popmax 0.00685%, nfe) (gnomAD).

What do computational predictors say about VGF p.Arg428Pro (c.1283G>C)?

AlphaMissense predicts likely benign (score 0.2385) — an in-silico prediction, not a clinical call.

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

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

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
