Is BRCA2 c.7007+329T>C pathogenic?

BRCA2 c.7007+329T>C is classified Benign in BRCA2 (ClinVar, Expert panel, 2 submitters; last evaluated 2015-01-12). Common (popmax 11.4%, sas) — too common for a highly-penetrant pathogenic allele; Associated with breast-ovarian cancer, familial, susceptibility to, 2.

What condition is associated with BRCA2 c.7007+329T>C?

BRCA2 c.7007+329T>C is associated with breast-ovarian cancer, familial, susceptibility to, 2 (ClinVar).

How is Hereditary breast and/or ovarian cancer syndrome inherited?

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

BRCA2 c.7007+329T>C

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.
