Is BAP1 p.Gly568= (c.1704G>A) pathogenic?

BAP1 p.Gly568= (c.1704G>A) is classified Benign/Likely benign in BAP1 (ClinVar, Multiple submitters, 3 submitters; last evaluated 2024-07-16). Very rare (popmax 0.00167%, amr); Associated with BAP1-related tumor predisposition syndrome.

What condition is associated with BAP1 p.Gly568= (c.1704G>A)?

BAP1 p.Gly568= (c.1704G>A) is associated with BAP1-related tumor predisposition syndrome, hereditary neoplastic syndrome (ClinVar).

How common is BAP1 p.Gly568= (c.1704G>A) in the general population?

BAP1 p.Gly568= (c.1704G>A) is very rare (popmax 0.00167%, amr) (gnomAD).

How is BAP1-related tumor predisposition syndrome inherited?

Typically Autosomal dominant (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.
