Is TES p.Arg89Cys (c.265C>T) pathogenic?

TES p.Arg89Cys (c.265C>T) is classified Uncertain significance in TES (ClinVar, Single submitter, 1 submitter; last evaluated 2024-09-30). AlphaMissense: likely pathogenic (0.7692); Very rare (popmax 0.00933%, afr).

How common is TES p.Arg89Cys (c.265C>T) in the general population?

TES p.Arg89Cys (c.265C>T) is very rare (popmax 0.00933%, afr) (gnomAD).

What do computational predictors say about TES p.Arg89Cys (c.265C>T)?

AlphaMissense predicts likely pathogenic (score 0.7692) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.7692	likely pathogenic
REVEL	0.466	indeterminate
SaProt	LLR -11.46	damaging
⇒ AlphaMissense and SaProt both call this damaging; REVEL makes no call.

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.
