Is COMTD1 p.Val10Met (c.28G>A) pathogenic?

COMTD1 p.Val10Met (c.28G>A) is classified Uncertain significance in COMTD1 (ClinVar, Single submitter, 1 submitter; last evaluated 2025-01-20). AlphaMissense: likely benign (0.172); Very rare (popmax 0.00329%, nfe).

How common is COMTD1 p.Val10Met (c.28G>A) in the general population?

COMTD1 p.Val10Met (c.28G>A) is very rare (popmax 0.00329%, nfe) (gnomAD).

What do computational predictors say about COMTD1 p.Val10Met (c.28G>A)?

AlphaMissense predicts likely benign (score 0.172) — an in-silico prediction, not a clinical call.

REVEL	0.071	moderately benign-leaning
SaProt	LLR -9.12	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.
