Is EYS p.Pro321Arg (c.962C>G) pathogenic?

EYS p.Pro321Arg (c.962C>G) is classified Uncertain significance in EYS (ClinVar, Single submitter, 2 submitters; last evaluated 2021-11-09). AlphaMissense: likely benign (0.0977); Absent from gnomAD v4.1; Associated with retinitis pigmentosa 25.

What condition is associated with EYS p.Pro321Arg (c.962C>G)?

EYS p.Pro321Arg (c.962C>G) is associated with retinitis pigmentosa 25 (ClinVar).

How common is EYS p.Pro321Arg (c.962C>G) in the general population?

EYS p.Pro321Arg (c.962C>G) 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.Pro321Arg (c.962C>G)?
