Is MPG p.Cys10Phe (c.29G>T) pathogenic?

MPG p.Cys10Phe (c.29G>T) is classified Uncertain significance in MPG (ClinVar, Single submitter, 1 submitter; last evaluated 2022-11-19). AlphaMissense: likely benign (0.0945); Ultra-rare (popmax 0.0164%, mid).

How common is MPG p.Cys10Phe (c.29G>T) in the general population?

MPG p.Cys10Phe (c.29G>T) is ultra-rare (popmax 0.0164%, mid) (gnomAD).

What do computational predictors say about MPG p.Cys10Phe (c.29G>T)?

AlphaMissense predicts likely benign (score 0.0945) — an in-silico prediction, not a clinical call.

⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

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.

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM C15F vs ClinVar C10F) — verify the residue.

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.
