Is BRCA1 p.Asp232= (c.696T>C) pathogenic?

BRCA1 p.Asp232= (c.696T>C) is classified Likely benign in BRCA1 (ClinVar, Multiple submitters, 5 submitters; last evaluated 2025-10-13). Very rare (popmax 6.2e-05%); Associated with hereditary breast ovarian cancer syndrome.

What condition is associated with BRCA1 p.Asp232= (c.696T>C)?

BRCA1 p.Asp232= (c.696T>C) is associated with hereditary breast ovarian cancer syndrome, breast-ovarian cancer, familial, susceptibility to, 1, hereditary neoplastic syndrome (ClinVar).

How common is BRCA1 p.Asp232= (c.696T>C) in the general population?

BRCA1 p.Asp232= (c.696T>C) is very rare (popmax 6.2e-05%) (gnomAD).

How is Hereditary breast and/or ovarian cancer 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.
