Is ACD p.Ala267Val (c.800C>T) pathogenic?

ACD p.Ala267Val (c.800C>T) is classified Uncertain significance in ACD (ClinVar, Single submitter, 1 submitter; last evaluated 2023-01-12). AlphaMissense: likely benign (0.1222); Very rare (popmax 8.63e-05%, nfe); Associated with Inborn genetic diseases.

What condition is associated with ACD p.Ala267Val (c.800C>T)?

ACD p.Ala267Val (c.800C>T) is associated with Inborn genetic diseases (ClinVar).

How common is ACD p.Ala267Val (c.800C>T) in the general population?

ACD p.Ala267Val (c.800C>T) is very rare (popmax 8.63e-05%, nfe) (gnomAD).

What do computational predictors say about ACD p.Ala267Val (c.800C>T)?

AlphaMissense predicts likely benign (score 0.1222) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.1222	likely benign
REVEL	0.071	moderately benign-leaning
SaProt	LLR -6.58	tolerated
⇒ AlphaMissense, REVEL and SaProt all call this tolerated.

Overall

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.
