Is BRCA1 p.Asn810Tyr (c.2428A>T) pathogenic?

BRCA1 p.Asn810Tyr (c.2428A>T) is classified Benign in BRCA1 (ClinVar, Expert panel, 18 submitters; last evaluated 2015-08-10). AlphaMissense: likely benign (0.1101); Ultra-rare (popmax 0.0145%, nfe); Associated with breast-ovarian cancer, familial, susceptibility to, 1.

What condition is associated with BRCA1 p.Asn810Tyr (c.2428A>T)?

BRCA1 p.Asn810Tyr (c.2428A>T) is associated with breast-ovarian cancer, familial, susceptibility to, 1, hereditary breast ovarian cancer syndrome, hereditary neoplastic syndrome (ClinVar).

How common is BRCA1 p.Asn810Tyr (c.2428A>T) in the general population?

BRCA1 p.Asn810Tyr (c.2428A>T) is ultra-rare (popmax 0.0145%, nfe) (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 BRCA1 p.Asn810Tyr (c.2428A>T)?

AlphaMissense predicts likely benign (score 0.1101) — 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.
