Is BOC p.Thr844Ser (c.2531C>G) pathogenic?

BOC p.Thr844Ser (c.2531C>G) is classified Uncertain significance in BOC (ClinVar, Single submitter, 1 submitter; last evaluated 2025-03-03). AlphaMissense: likely benign (0.1344); Very rare (popmax 0.000508%, nfe).

How common is BOC p.Thr844Ser (c.2531C>G) in the general population?

BOC p.Thr844Ser (c.2531C>G) is very rare (popmax 0.000508%, nfe) (gnomAD).

What do computational predictors say about BOC p.Thr844Ser (c.2531C>G)?

AlphaMissense predicts likely benign (score 0.1344) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.1344	likely benign
REVEL	0.048	moderately benign-leaning
SaProt	LLR -5.63	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.

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM T843S vs ClinVar T844S) — verify the residue.

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.
