Is DYSF p.Ile286Ser (c.857T>G) pathogenic?

DYSF p.Ile286Ser (c.857T>G) is classified Uncertain significance in DYSF (ClinVar, Multiple submitters, 3 submitters; last evaluated 2025-11-25). AlphaMissense: likely pathogenic (0.8636); Very rare (popmax 0.00186%, nfe); Associated with Inborn genetic diseases.

What condition is associated with DYSF p.Ile286Ser (c.857T>G)?

DYSF p.Ile286Ser (c.857T>G) is associated with Inborn genetic diseases, neuromuscular disease caused by qualitative or quantitative defects of dysferlin (ClinVar).

How common is DYSF p.Ile286Ser (c.857T>G) in the general population?

DYSF p.Ile286Ser (c.857T>G) is very rare (popmax 0.00186%, nfe) (gnomAD).

What do computational predictors say about DYSF p.Ile286Ser (c.857T>G)?

AlphaMissense predicts likely pathogenic (score 0.8636) — an in-silico prediction, not a clinical call.

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM I254S vs ClinVar I286S) — 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.
