Is VHL p.Ser68Pro (c.202T>C) pathogenic?

VHL p.Ser68Pro (c.202T>C) is classified Pathogenic in VHL (ClinVar, Single submitter, 1 submitter; last evaluated 2024-01-02). AlphaMissense: likely pathogenic (0.932); Absent from gnomAD v4.1; Associated with von Hippel-Lindau disease.

What condition is associated with VHL p.Ser68Pro (c.202T>C)?

VHL p.Ser68Pro (c.202T>C) is associated with von Hippel-Lindau disease, Chuvash polycythemia (ClinVar).

How common is VHL p.Ser68Pro (c.202T>C) in the general population?

VHL p.Ser68Pro (c.202T>C) is absent from gnomAD v4.1 (gnomAD).

How is Von Hippel-Lindau disease inherited?

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

What do computational predictors say about VHL p.Ser68Pro (c.202T>C)?

AlphaMissense predicts likely pathogenic (score 0.932) — an in-silico prediction, not a clinical call.
