Is BRIP1 p.Ile784Val (c.2350A>G) pathogenic?

BRIP1 p.Ile784Val (c.2350A>G) is classified Uncertain significance in BRIP1 (ClinVar, Single submitter, 1 submitter; last evaluated 2025-09-13). AlphaMissense: ambiguous (0.3473); Absent from gnomAD v4.1; Associated with hereditary breast carcinoma.

What condition is associated with BRIP1 p.Ile784Val (c.2350A>G)?

BRIP1 p.Ile784Val (c.2350A>G) is associated with hereditary breast carcinoma, Fanconi anemia complementation group J (ClinVar).

How common is BRIP1 p.Ile784Val (c.2350A>G) in the general population?

BRIP1 p.Ile784Val (c.2350A>G) is absent from gnomAD v4.1 (gnomAD).

How is Hereditary breast cancer inherited?

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

What do computational predictors say about BRIP1 p.Ile784Val (c.2350A>G)?

AlphaMissense predicts ambiguous (score 0.3473) — an in-silico prediction, not a clinical call.
