Is PASK p.Ala92Pro (c.274G>C) pathogenic?

PASK p.Ala92Pro (c.274G>C) is classified Uncertain significance in PASK (ClinVar, Single submitter, 2 submitters; last evaluated 2025-08-07). AlphaMissense: likely benign (0.0828); Rare (popmax 0.199%, afr).

How common is PASK p.Ala92Pro (c.274G>C) in the general population?

PASK p.Ala92Pro (c.274G>C) is rare (popmax 0.199%, afr) (gnomAD).

What do computational predictors say about PASK p.Ala92Pro (c.274G>C)?

AlphaMissense predicts likely benign (score 0.0828) — an in-silico prediction, not a clinical call.

REVEL	0.226	benign-leaning
SaProt	LLR -6.52	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.
