Is EYS p.Cys211Phe (c.632G>T) pathogenic?

EYS p.Cys211Phe (c.632G>T) is classified Conflicting classifications of pathogenicity in EYS (ClinVar, Conflicting submitters, 3 submitters; last evaluated 2026-01-25). AlphaMissense: likely pathogenic (0.5962); Rare (popmax 0.135%, amr); Associated with retinitis pigmentosa 25.

What condition is associated with EYS p.Cys211Phe (c.632G>T)?

EYS p.Cys211Phe (c.632G>T) is associated with retinitis pigmentosa 25 (ClinVar).

How common is EYS p.Cys211Phe (c.632G>T) in the general population?

EYS p.Cys211Phe (c.632G>T) is rare (popmax 0.135%, amr) (gnomAD).

How is Retinitis pigmentosa inherited?

Typically Autosomal dominant, Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about EYS p.Cys211Phe (c.632G>T)?

AlphaMissense predicts likely pathogenic (score 0.5962) — an in-silico prediction, not a clinical call.

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.
