Is CEMIP p.Asp771Asn (c.2311G>A) pathogenic?

CEMIP p.Asp771Asn (c.2311G>A) is classified Uncertain significance in CEMIP (ClinVar, Single submitter, 1 submitter; last evaluated 2022-12-28). AlphaMissense: likely benign (0.0947); Very rare (popmax 0.005%, amr).

How common is CEMIP p.Asp771Asn (c.2311G>A) in the general population?

CEMIP p.Asp771Asn (c.2311G>A) is very rare (popmax 0.005%, amr) (gnomAD).

What do computational predictors say about CEMIP p.Asp771Asn (c.2311G>A)?

AlphaMissense predicts likely benign (score 0.0947) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0947	likely benign
REVEL	0.295	indeterminate
SaProt	LLR -8.01	tolerated
⇒ AlphaMissense and SaProt both call this tolerated; REVEL makes no 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.
