Is PGC p.Val212Ala (c.635T>C) pathogenic?

PGC p.Val212Ala (c.635T>C) is classified Uncertain significance in PGC (ClinVar, Single submitter, 1 submitter; last evaluated 2025-10-24). AlphaMissense: likely pathogenic (0.6698); Very rare (popmax 0.00801%, afr).

How common is PGC p.Val212Ala (c.635T>C) in the general population?

PGC p.Val212Ala (c.635T>C) is very rare (popmax 0.00801%, afr) (gnomAD).

What do computational predictors say about PGC p.Val212Ala (c.635T>C)?

AlphaMissense predicts likely pathogenic (score 0.6698) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change
AlphaMissense	0.6698	likely pathogenic
REVEL	0.404	indeterminate
SaProt	LLR -11.65	damaging
⇒ AlphaMissense and SaProt both call this damaging; REVEL is indeterminate.
Splicing
SpliceAI	<0.2	no splice effect predicted · four deltas, not one · how we know

Regional constraint	o/e 0.97	unconstrained · MANE · 10 kb · p 0.46 · regional, not allelic
Overall
CADD	23.9	PHRED · no single calibrated threshold — expert panels disagree

ClinVar classifies this uncertain; the computational predictors unanimously lean damaging — 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.
