Is CAVIN4 p.Val68Ile (c.202G>A) pathogenic?

CAVIN4 p.Val68Ile (c.202G>A) is classified Uncertain significance in CAVIN4 (ClinVar, Single submitter, 1 submitter; last evaluated 2022-08-12). AlphaMissense: likely benign (0.0959); Ultra-rare (popmax 0.0164%, mid).

How common is CAVIN4 p.Val68Ile (c.202G>A) in the general population?

CAVIN4 p.Val68Ile (c.202G>A) is ultra-rare (popmax 0.0164%, mid) (gnomAD).

What do computational predictors say about CAVIN4 p.Val68Ile (c.202G>A)?

AlphaMissense predicts likely benign (score 0.0959) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0959	likely benign
REVEL	0.119	moderately benign-leaning
SaProt	LLR -6.21	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.
