Is EYS p.Phe2954Ser (c.8861T>C) pathogenic?

EYS p.Phe2954Ser (c.8861T>C) is classified Likely pathogenic in EYS (ClinVar, Single submitter, 1 submitter; last evaluated 2025-05-15). AlphaMissense: likely pathogenic (0.7442); Absent from gnomAD v4.1; Associated with retinitis pigmentosa 25.

What condition is associated with EYS p.Phe2954Ser (c.8861T>C)?

EYS p.Phe2954Ser (c.8861T>C) is associated with retinitis pigmentosa 25 (ClinVar).

How common is EYS p.Phe2954Ser (c.8861T>C) in the general population?

EYS p.Phe2954Ser (c.8861T>C) is absent from gnomAD v4.1 (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.Phe2954Ser (c.8861T>C)?

AlphaMissense predicts likely pathogenic (score 0.7442) — an in-silico prediction, not a clinical call.

AlphaMissense carries the ACMG weight for missense; REVEL is an independent agreement signal.

⚠ Isoform check: AlphaMissense numbered on a different transcript (AM F2975S vs ClinVar F2954S) — verify the residue.
