Is CEBPA p.Pro51Ser (c.151C>T) pathogenic?

CEBPA p.Pro51Ser (c.151C>T) is classified Uncertain significance in CEBPA (ClinVar, Multiple submitters, 3 submitters; last evaluated 2025-09-25). AlphaMissense: likely benign (0.0816); Very rare (popmax 0.00292%, eas); Associated with Inborn genetic diseases.

What condition is associated with CEBPA p.Pro51Ser (c.151C>T)?

CEBPA p.Pro51Ser (c.151C>T) is associated with Inborn genetic diseases, acute myeloid leukemia (ClinVar).

How common is CEBPA p.Pro51Ser (c.151C>T) in the general population?

CEBPA p.Pro51Ser (c.151C>T) is very rare (popmax 0.00292%, eas) (gnomAD).

What do computational predictors say about CEBPA p.Pro51Ser (c.151C>T)?

AlphaMissense predicts likely benign (score 0.0816) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change
AlphaMissense	0.0816	likely benign
REVEL	0.074	moderately benign-leaning
SaProt	LLR -7.76	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

Overall
CADD	21.0	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.
