What condition is associated with PKD2 p.Phe358Ser (c.1073T>C)?

PKD2 p.Phe358Ser (c.1073T>C) is associated with polycystic kidney disease 2 (ClinVar).

How common is PKD2 p.Phe358Ser (c.1073T>C) in the general population?

PKD2 p.Phe358Ser (c.1073T>C) is absent from gnomAD v4.1 (gnomAD).

How is Autosomal dominant polycystic kidney disease inherited?

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

What do computational predictors say about PKD2 p.Phe358Ser (c.1073T>C)?

AlphaMissense predicts likely pathogenic (score 0.7861) — an in-silico prediction, not a clinical call.
