Is CENPH p.Asp84Ala (c.251A>C) pathogenic?

CENPH p.Asp84Ala (c.251A>C) is classified Uncertain significance in CENPH (ClinVar, Single submitter, 1 submitter; last evaluated 2025-09-01). AlphaMissense: likely benign (0.1145); Very rare (popmax 0.000789%, nfe).

How common is CENPH p.Asp84Ala (c.251A>C) in the general population?

CENPH p.Asp84Ala (c.251A>C) is very rare (popmax 0.000789%, nfe) (gnomAD).

What do computational predictors say about CENPH p.Asp84Ala (c.251A>C)?

AlphaMissense predicts likely benign (score 0.1145) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change
AlphaMissense	0.1145	likely benign
REVEL	0.04	moderately benign-leaning
SaProt	LLR -5.19	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.
