Is BMP6 p.Ile83Met (c.249C>G) pathogenic?

BMP6 p.Ile83Met (c.249C>G) is classified Uncertain significance in BMP6 (ClinVar, Single submitter, 1 submitter; last evaluated 2024-10-01). AlphaMissense: likely pathogenic (0.9235); Ultra-rare (popmax 0.0166%, mid).

How common is BMP6 p.Ile83Met (c.249C>G) in the general population?

BMP6 p.Ile83Met (c.249C>G) is ultra-rare (popmax 0.0166%, mid) (gnomAD).

What do computational predictors say about BMP6 p.Ile83Met (c.249C>G)?

AlphaMissense predicts likely pathogenic (score 0.9235) — an in-silico prediction, not a clinical call.

ClinVar classifies this uncertain; the computational predictors unanimously lean damaging — 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.
