Is BRCA2 p.Asp244Tyr (c.730G>T) pathogenic?

BRCA2 p.Asp244Tyr (c.730G>T) is classified Uncertain significance in BRCA2 (ClinVar, Multiple submitters, 5 submitters; last evaluated 2024-12-06). AlphaMissense: likely benign (0.1079); Very rare (popmax 0.00161%, nfe); Associated with hereditary breast ovarian cancer syndrome.

What condition is associated with BRCA2 p.Asp244Tyr (c.730G>T)?

BRCA2 p.Asp244Tyr (c.730G>T) is associated with hereditary breast ovarian cancer syndrome, hereditary neoplastic syndrome, BRCA2-related cancer predisposition (ClinVar).

How common is BRCA2 p.Asp244Tyr (c.730G>T) in the general population?

BRCA2 p.Asp244Tyr (c.730G>T) is very rare (popmax 0.00161%, 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 BRCA2 p.Asp244Tyr (c.730G>T)?

AlphaMissense predicts likely benign (score 0.1079) — an in-silico prediction, not a clinical call.

Protein change
AlphaMissense	0.1079	likely benign
REVEL	0.13	moderately benign-leaning
⇒ AlphaMissense and REVEL both call this tolerated.

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.
