Is BRCA1 p.Asp1573His (c.4717G>C) pathogenic?

BRCA1 p.Asp1573His (c.4717G>C) is classified Uncertain significance in BRCA1 (ClinVar, Multiple submitters, 4 submitters; last evaluated 2024-08-07). AlphaMissense: likely benign (0.1301); Very rare (popmax 0.00133%, afr); Associated with hereditary breast ovarian cancer syndrome.

What condition is associated with BRCA1 p.Asp1573His (c.4717G>C)?

BRCA1 p.Asp1573His (c.4717G>C) is associated with hereditary breast ovarian cancer syndrome, hereditary neoplastic syndrome (ClinVar).

How common is BRCA1 p.Asp1573His (c.4717G>C) in the general population?

BRCA1 p.Asp1573His (c.4717G>C) is very rare (popmax 0.00133%, afr) (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.Asp1573His (c.4717G>C)?

AlphaMissense predicts likely benign (score 0.1301) — an in-silico prediction, not a clinical call.

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

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.
