Is ENTREP1 p.Pro302Ala (c.904C>G) pathogenic?

ENTREP1 p.Pro302Ala (c.904C>G) is classified Uncertain significance in ENTREP1 (ClinVar, Single submitter, 1 submitter; last evaluated 2023-01-26). AlphaMissense: likely pathogenic (0.6536); Very rare (popmax 0.000593%, nfe).

How common is ENTREP1 p.Pro302Ala (c.904C>G) in the general population?

ENTREP1 p.Pro302Ala (c.904C>G) is very rare (popmax 0.000593%, nfe) (gnomAD).

What do computational predictors say about ENTREP1 p.Pro302Ala (c.904C>G)?

AlphaMissense predicts likely pathogenic (score 0.6536) — an in-silico prediction, not a clinical call.

ClinVar classifies this uncertain; the computational predictors unanimously lean damaging — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM P149A vs ClinVar P302A) — verify the residue.

Remaining individuals shows a higher raw frequency than the grpmax group above it. gnomAD excludes bottlenecked groups — Finnish, Ashkenazi Jewish, Amish and “Remaining individuals” — from grpmax, because founder effects make their frequencies unrepresentative for filtering. The table is sorted by frequency, so an excluded group can sit above the grpmax row.

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.
