Is REL p.Asp338His (c.1012G>C) pathogenic?

REL p.Asp338His (c.1012G>C) is classified Uncertain significance in REL (ClinVar, Single submitter, 1 submitter; last evaluated 2025-11-08). AlphaMissense: likely benign (0.1702); Very rare (popmax 0.00402%, afr).

How common is REL p.Asp338His (c.1012G>C) in the general population?

REL p.Asp338His (c.1012G>C) is very rare (popmax 0.00402%, afr) (gnomAD).

What do computational predictors say about REL p.Asp338His (c.1012G>C)?

AlphaMissense predicts likely benign (score 0.1702) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.1702	likely benign
REVEL	0.028	moderately benign-leaning
SaProt	LLR -6.64	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.

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM D370H vs ClinVar D338H) — verify the residue.

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.
