Is SET p.Thr108Ser (c.323C>G) pathogenic?

SET p.Thr108Ser (c.323C>G) is classified Uncertain significance in SET (ClinVar, Single submitter, 1 submitter; last evaluated 2024-02-07). AlphaMissense: likely benign (0.1503); Absent from gnomAD v4.1.

How common is SET p.Thr108Ser (c.323C>G) in the general population?

SET p.Thr108Ser (c.323C>G) is absent from gnomAD v4.1 (gnomAD).

What do computational predictors say about SET p.Thr108Ser (c.323C>G)?

AlphaMissense predicts likely benign (score 0.1503) — 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 T121S vs ClinVar T108S) — verify the residue.
