Is TRIM32 p.Pro270Ser (c.808C>T) pathogenic?

TRIM32 p.Pro270Ser (c.808C>T) is classified Uncertain significance in TRIM32 (ClinVar, Single submitter, 1 submitter; last evaluated 2024-06-22). AlphaMissense: likely benign (0.1801); Absent from gnomAD v4.1; Associated with Bardet-Biedl syndrome.

What condition is associated with TRIM32 p.Pro270Ser (c.808C>T)?

TRIM32 p.Pro270Ser (c.808C>T) is associated with Bardet-Biedl syndrome (ClinVar).

How common is TRIM32 p.Pro270Ser (c.808C>T) in the general population?

TRIM32 p.Pro270Ser (c.808C>T) is absent from gnomAD v4.1 (gnomAD).

How is Bardet-Biedl syndrome inherited?

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

What do computational predictors say about TRIM32 p.Pro270Ser (c.808C>T)?

AlphaMissense predicts likely benign (score 0.1801) — an in-silico prediction, not a clinical call.

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

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