Is BFAR p.Ser337Cys (c.1010C>G) pathogenic?

BFAR p.Ser337Cys (c.1010C>G) is classified Uncertain significance in BFAR (ClinVar, Single submitter, 1 submitter; last evaluated 2021-08-17). AlphaMissense: likely benign (0.0572); Very rare (popmax 0.00339%, nfe).

How common is BFAR p.Ser337Cys (c.1010C>G) in the general population?

BFAR p.Ser337Cys (c.1010C>G) is very rare (popmax 0.00339%, nfe) (gnomAD).

What do computational predictors say about BFAR p.Ser337Cys (c.1010C>G)?

AlphaMissense predicts likely benign (score 0.0572) — an in-silico prediction, not a clinical 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.
