Is BRCA2 p.Arg2842Ser (c.8524C>A) pathogenic?

BRCA2 p.Arg2842Ser (c.8524C>A) is classified Uncertain significance in BRCA2 (ClinVar, Multiple submitters, 2 submitters; last evaluated 2019-12-30). AlphaMissense: likely pathogenic (0.9851); Absent from gnomAD v4.1; Associated with hereditary breast ovarian cancer syndrome.

What condition is associated with BRCA2 p.Arg2842Ser (c.8524C>A)?

BRCA2 p.Arg2842Ser (c.8524C>A) is associated with hereditary breast ovarian cancer syndrome, hereditary neoplastic syndrome (ClinVar).

How common is BRCA2 p.Arg2842Ser (c.8524C>A) in the general population?

BRCA2 p.Arg2842Ser (c.8524C>A) is absent from gnomAD v4.1 (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.Arg2842Ser (c.8524C>A)?

AlphaMissense predicts likely pathogenic (score 0.9851) — an in-silico prediction, not a clinical call.

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

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