AlphaMissense: likely benign (0.1317); Ultra-rare (popmax 0.0914%, eas); Associated with hereditary breast ovarian cancer syndrome.

What condition is associated with BRCA2 p.Asp1990Ala (c.5969A>C)?

BRCA2 p.Asp1990Ala (c.5969A>C) is associated with hereditary breast ovarian cancer syndrome, breast-ovarian cancer, familial, susceptibility to, 2, hereditary neoplastic syndrome (ClinVar).

How common is BRCA2 p.Asp1990Ala (c.5969A>C) in the general population?

BRCA2 p.Asp1990Ala (c.5969A>C) is ultra-rare (popmax 0.0914%, eas) (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.

What do computational predictors say about BRCA2 p.Asp1990Ala (c.5969A>C)?

AlphaMissense predicts likely benign (score 0.1317) — an in-silico prediction, not a clinical call.

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.
