How common is RHBDF2 p.Cys129Ser (c.386G>C) in the general population?

RHBDF2 p.Cys129Ser (c.386G>C) is very rare (popmax 0.005%, amr) (gnomAD).

What do computational predictors say about RHBDF2 p.Cys129Ser (c.386G>C)?

AlphaMissense predicts likely benign (score 0.1537) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.1537	likely benign
REVEL	0.045	moderately benign-leaning
SaProt	LLR -4.04	tolerated
⇒ 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 C158S vs ClinVar C129S) — 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.
