Is SLMAP p.Arg810Gln (c.2429G>A) pathogenic?

SLMAP p.Arg810Gln (c.2429G>A) is classified Uncertain significance in SLMAP (ClinVar, Multiple submitters, 2 submitters; last evaluated 2025-08-09). AlphaMissense: likely benign (0.056); Very rare (popmax 0.00668%, amr); Associated with Brugada syndrome.

What condition is associated with SLMAP p.Arg810Gln (c.2429G>A)?

SLMAP p.Arg810Gln (c.2429G>A) is associated with Brugada syndrome (ClinVar).

How common is SLMAP p.Arg810Gln (c.2429G>A) in the general population?

SLMAP p.Arg810Gln (c.2429G>A) is very rare (popmax 0.00668%, amr) (gnomAD).

How is Brugada syndrome inherited?

Typically Autosomal dominant, Not applicable (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about SLMAP p.Arg810Gln (c.2429G>A)?

AlphaMissense predicts likely benign (score 0.056) — an in-silico prediction, not a clinical call.

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 R793Q vs ClinVar R810Q) — 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.
