Is CMIP p.Gly9Ala (c.26G>C) pathogenic?

CMIP p.Gly9Ala (c.26G>C) is classified Uncertain significance in CMIP (ClinVar, Single submitter, 1 submitter; last evaluated 2024-09-24). AlphaMissense: likely benign (0.0987); Very rare (popmax 0.00197%, amr).

How common is CMIP p.Gly9Ala (c.26G>C) in the general population?

CMIP p.Gly9Ala (c.26G>C) is very rare (popmax 0.00197%, amr) (gnomAD).

What do computational predictors say about CMIP p.Gly9Ala (c.26G>C)?

AlphaMissense predicts likely benign (score 0.0987) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0987	likely benign
REVEL	0.15	moderately benign-leaning
SaProt	LLR -6.88	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.
