Is SERPINE1 p.Ile282Ser (c.845T>G) pathogenic?

SERPINE1 p.Ile282Ser (c.845T>G) is classified Uncertain significance in SERPINE1 (ClinVar, Single submitter, 1 submitter; last evaluated 2018-01-13). AlphaMissense: likely pathogenic (0.917); Absent from gnomAD v4.1; Associated with congenital plasminogen activator inhibitor type 1 deficiency.

What condition is associated with SERPINE1 p.Ile282Ser (c.845T>G)?

SERPINE1 p.Ile282Ser (c.845T>G) is associated with congenital plasminogen activator inhibitor type 1 deficiency (ClinVar).

How common is SERPINE1 p.Ile282Ser (c.845T>G) in the general population?

SERPINE1 p.Ile282Ser (c.845T>G) is absent from gnomAD v4.1 (gnomAD).

What do computational predictors say about SERPINE1 p.Ile282Ser (c.845T>G)?

ClinVar classifies this uncertain; the computational predictors unanimously lean damaging — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.
