Is BARD1 p.Val755= (c.2265C>A) pathogenic?

BARD1 p.Val755= (c.2265C>A) is classified Likely benign in BARD1 (ClinVar, Single submitter, 1 submitter; last evaluated 2025-07-19). Very rare (popmax 0.00133%, afr); Associated with hereditary breast carcinoma.

What condition is associated with BARD1 p.Val755= (c.2265C>A)?

BARD1 p.Val755= (c.2265C>A) is associated with hereditary breast carcinoma (ClinVar).

How common is BARD1 p.Val755= (c.2265C>A) in the general population?

BARD1 p.Val755= (c.2265C>A) is very rare (popmax 0.00133%, afr) (gnomAD).

How is Hereditary breast cancer inherited?

Typically Autosomal dominant, Multigenic/multifactorial (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.
