What condition is associated with BRCA2 p.Glu804= (c.2412A>G)?

BRCA2 p.Glu804= (c.2412A>G) is associated with breast-ovarian cancer, familial, susceptibility to, 2, hereditary breast ovarian cancer syndrome, Fanconi anemia complementation group D1 (ClinVar).

How common is BRCA2 p.Glu804= (c.2412A>G) in the general population?

BRCA2 p.Glu804= (c.2412A>G) is rare (popmax 0.106%, amr) (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.
