Is DYSF p.Val69Met (c.205G>A) pathogenic?

DYSF p.Val69Met (c.205G>A) is classified Uncertain significance in DYSF (ClinVar, Single submitter, 1 submitter; last evaluated 2021-09-01). AlphaMissense: likely benign (0.2163); Very rare (popmax 0.00127%, nfe); Associated with neuromuscular disease caused by qualitative or quantitative defects of dysferlin.

How common is DYSF p.Val69Met (c.205G>A) in the general population?

DYSF p.Val69Met (c.205G>A) is very rare (popmax 0.00127%, nfe) (gnomAD).

What do computational predictors say about DYSF p.Val69Met (c.205G>A)?

AlphaMissense predicts likely benign (score 0.2163) — an in-silico prediction, not a clinical call.

Protein change

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 V68M vs ClinVar V69M) — 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.
