Is CDX2 p.Pro35Thr (c.103C>A) pathogenic?

CDX2 p.Pro35Thr (c.103C>A) is classified Uncertain significance in CDX2 (ClinVar, Single submitter, 1 submitter; last evaluated 2024-07-02). AlphaMissense: likely benign (0.2764); Rare (popmax 0.151%, afr).

How common is CDX2 p.Pro35Thr (c.103C>A) in the general population?

CDX2 p.Pro35Thr (c.103C>A) is rare (popmax 0.151%, afr) (gnomAD).

What do computational predictors say about CDX2 p.Pro35Thr (c.103C>A)?

AlphaMissense predicts likely benign (score 0.2764) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.2764	likely benign
REVEL	0.279	benign-leaning
SaProt	LLR -7.26	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.

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.
