Is BRCA1 p.Asp693Tyr (c.2077G>T) pathogenic?

BRCA1 p.Asp693Tyr (c.2077G>T) is classified Benign in BRCA1 (ClinVar, No assertion criteria, 1 submitter; last evaluated 2010-12-17). AlphaMissense: likely benign (0.0802); Absent from gnomAD v4.1; Associated with breast-ovarian cancer, familial, susceptibility to, 1.

What condition is associated with BRCA1 p.Asp693Tyr (c.2077G>T)?

BRCA1 p.Asp693Tyr (c.2077G>T) is associated with breast-ovarian cancer, familial, susceptibility to, 1 (ClinVar).

How common is BRCA1 p.Asp693Tyr (c.2077G>T) in the general population?

BRCA1 p.Asp693Tyr (c.2077G>T) is absent from gnomAD v4.1 (gnomAD).
