What condition is associated with BRCA1 p.Arg610Ser (c.1830G>T)?

BRCA1 p.Arg610Ser (c.1830G>T) is associated with hereditary breast ovarian cancer syndrome, hereditary neoplastic syndrome (ClinVar).

How common is BRCA1 p.Arg610Ser (c.1830G>T) in the general population?

BRCA1 p.Arg610Ser (c.1830G>T) 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 BRCA1 p.Arg610Ser (c.1830G>T)?

AlphaMissense predicts ambiguous (score 0.4465) — an in-silico prediction, not a clinical call.
