Is SORT1 p.Leu32Pro (c.95T>C) pathogenic?

SORT1 p.Leu32Pro (c.95T>C) is classified Uncertain significance in SORT1 (ClinVar, Single submitter, 1 submitter; last evaluated 2025-11-20). AlphaMissense: likely benign (0.0552); Very rare (popmax 0.00158%, afr).

How common is SORT1 p.Leu32Pro (c.95T>C) in the general population?

SORT1 p.Leu32Pro (c.95T>C) is very rare (popmax 0.00158%, afr) (gnomAD).

What do computational predictors say about SORT1 p.Leu32Pro (c.95T>C)?

AlphaMissense predicts likely benign (score 0.0552) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.0552	likely benign
REVEL	0.056	moderately benign-leaning
SaProt	LLR -7.58	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.
