Is CLUH p.Cys45Trp (c.135C>G) pathogenic?

CLUH p.Cys45Trp (c.135C>G) is classified Uncertain significance in CLUH (ClinVar, Single submitter, 1 submitter; last evaluated 2025-10-28). AlphaMissense: likely benign (0.1877); Very rare (popmax 8.6e-05%, nfe).

How common is CLUH p.Cys45Trp (c.135C>G) in the general population?

CLUH p.Cys45Trp (c.135C>G) is very rare (popmax 8.6e-05%, nfe) (gnomAD).

What do computational predictors say about CLUH p.Cys45Trp (c.135C>G)?

AlphaMissense predicts likely benign (score 0.1877) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change
AlphaMissense	0.1877	likely benign
REVEL	0.405	indeterminate
SaProt	LLR -8.94	tolerated
⇒ AlphaMissense and SaProt both call this tolerated; REVEL makes no 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 C7W vs ClinVar C45W) — verify the residue.

Population frequency

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.
