Is BFAR p.Ile106Val (c.316A>G) pathogenic?

BFAR p.Ile106Val (c.316A>G) is classified Uncertain significance in BFAR (ClinVar, Single submitter, 1 submitter; last evaluated 2025-05-19). AlphaMissense: likely benign (0.1277); Ultra-rare (popmax 0.0167%, amr).

How common is BFAR p.Ile106Val (c.316A>G) in the general population?

BFAR p.Ile106Val (c.316A>G) is ultra-rare (popmax 0.0167%, amr) (gnomAD).

What do computational predictors say about BFAR p.Ile106Val (c.316A>G)?

AlphaMissense predicts likely benign (score 0.1277) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.1277	likely benign
REVEL	0.096	moderately benign-leaning
SaProt	LLR -5.14	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.
