What condition is associated with EMX2 p.Ser27Ala (c.79T>G)?

EMX2 p.Ser27Ala (c.79T>G) is associated with Inborn genetic diseases (ClinVar).

How common is EMX2 p.Ser27Ala (c.79T>G) in the general population?

EMX2 p.Ser27Ala (c.79T>G) is very rare (popmax 0.00136%, afr) (gnomAD).

What do computational predictors say about EMX2 p.Ser27Ala (c.79T>G)?

AlphaMissense predicts likely benign (score 0.064) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change
AlphaMissense	0.064	likely benign
REVEL	0.302	indeterminate
SaProt	LLR -6.41	tolerated
⇒ AlphaMissense and SaProt both call this tolerated; REVEL makes no call.

Overall
CADD	23.3	PHRED · no single calibrated threshold — expert panels disagree

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.
