Is PTEN p.His376Pro (c.1127A>C) pathogenic?

PTEN p.His376Pro (c.1127A>C) is classified Uncertain significance in PTEN (ClinVar, Single submitter, 1 submitter; last evaluated 2024-10-02). AlphaMissense: likely benign (0.258); Absent from gnomAD v4.1; Associated with PTEN hamartoma tumor syndrome.

What condition is associated with PTEN p.His376Pro (c.1127A>C)?

PTEN p.His376Pro (c.1127A>C) is associated with PTEN hamartoma tumor syndrome (ClinVar).

How common is PTEN p.His376Pro (c.1127A>C) in the general population?

PTEN p.His376Pro (c.1127A>C) is absent from gnomAD v4.1 (gnomAD).

How is PTEN hamartoma tumor syndrome inherited?

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

What do computational predictors say about PTEN p.His376Pro (c.1127A>C)?

AlphaMissense predicts likely benign (score 0.258) — an in-silico prediction, not a clinical call.
