Is CCK p.Val13Ile (c.37G>A) pathogenic?

CCK p.Val13Ile (c.37G>A) is classified Uncertain significance in CCK (ClinVar, Single submitter, 1 submitter; last evaluated 2025-01-17). AlphaMissense: likely benign (0.1067); Very rare (popmax 0.00936%, afr).

How common is CCK p.Val13Ile (c.37G>A) in the general population?

CCK p.Val13Ile (c.37G>A) is very rare (popmax 0.00936%, afr) (gnomAD).

What do computational predictors say about CCK p.Val13Ile (c.37G>A)?

AlphaMissense predicts likely benign (score 0.1067) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.1067	likely benign
REVEL	0.106	moderately benign-leaning
SaProt	LLR -7.99	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.
