Is DNPEP p.Pro155Ser (c.463C>T) pathogenic?

DNPEP p.Pro155Ser (c.463C>T) is classified Uncertain significance in DNPEP (ClinVar, Single submitter, 1 submitter; last evaluated 2023-02-16). AlphaMissense: likely benign (0.0815); Very rare (popmax 0.005%, amr).

How common is DNPEP p.Pro155Ser (c.463C>T) in the general population?

DNPEP p.Pro155Ser (c.463C>T) is very rare (popmax 0.005%, amr) (gnomAD).

What do computational predictors say about DNPEP p.Pro155Ser (c.463C>T)?

AlphaMissense predicts likely benign (score 0.0815) — an in-silico prediction, not a clinical call.

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.
