Is TRIM32 p.Arg180= (c.540G>A) pathogenic?

TRIM32 p.Arg180= (c.540G>A) is classified Likely benign in TRIM32 (ClinVar, Single submitter, 1 submitter; last evaluated 2020-12-08). Very rare (popmax 8.47e-05%, nfe); Associated with Bardet-Biedl syndrome.

What condition is associated with TRIM32 p.Arg180= (c.540G>A)?

TRIM32 p.Arg180= (c.540G>A) is associated with Bardet-Biedl syndrome (ClinVar).

How common is TRIM32 p.Arg180= (c.540G>A) in the general population?

TRIM32 p.Arg180= (c.540G>A) is very rare (popmax 8.47e-05%, nfe) (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.
