Is TRIM32 p.Ala2= (c.6T>G) pathogenic?

TRIM32 p.Ala2= (c.6T>G) is classified Conflicting classifications of pathogenicity in TRIM32 (ClinVar, Conflicting submitters, 6 submitters; last evaluated 2026-01-19). Rare (popmax 0.277%, afr); Associated with Bardet-Biedl syndrome.

What condition is associated with TRIM32 p.Ala2= (c.6T>G)?

TRIM32 p.Ala2= (c.6T>G) is associated with Bardet-Biedl syndrome (ClinVar).

How common is TRIM32 p.Ala2= (c.6T>G) in the general population?

TRIM32 p.Ala2= (c.6T>G) is rare (popmax 0.277%, afr) (gnomAD).

How is Bardet-Biedl syndrome inherited?

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

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
