Is BAP1 p.Ser292Cys (c.875C>G) pathogenic?

BAP1 p.Ser292Cys (c.875C>G) is classified Conflicting classifications of pathogenicity in BAP1 (ClinVar, Conflicting submitters, 3 submitters; last evaluated 2025-11-20). AlphaMissense: likely benign (0.0891); Very rare (popmax 0.00314%, nfe); Associated with BAP1-related tumor predisposition syndrome.

What condition is associated with BAP1 p.Ser292Cys (c.875C>G)?

BAP1 p.Ser292Cys (c.875C>G) is associated with BAP1-related tumor predisposition syndrome, hereditary neoplastic syndrome (ClinVar).

How common is BAP1 p.Ser292Cys (c.875C>G) in the general population?

BAP1 p.Ser292Cys (c.875C>G) is very rare (popmax 0.00314%, nfe) (gnomAD).

How is BAP1-related tumor predisposition syndrome inherited?

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

What do computational predictors say about BAP1 p.Ser292Cys (c.875C>G)?

AlphaMissense predicts likely benign (score 0.0891) — an in-silico prediction, not a clinical call.

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.
