Is CDS2 p.Ser307Leu (c.920C>T) pathogenic?

CDS2 p.Ser307Leu (c.920C>T) is classified Uncertain significance in CDS2 (ClinVar, Single submitter, 1 submitter; last evaluated 2024-07-09). AlphaMissense: likely benign (0.175); Very rare (popmax 0.0022%, sas).

How common is CDS2 p.Ser307Leu (c.920C>T) in the general population?

CDS2 p.Ser307Leu (c.920C>T) is very rare (popmax 0.0022%, sas) (gnomAD).

What do computational predictors say about CDS2 p.Ser307Leu (c.920C>T)?

AlphaMissense predicts likely benign (score 0.175) — an in-silico prediction, not a clinical call.

REVEL	0.274	benign-leaning
SaProt	LLR -8.09	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.
