Is BRCA2 p.Gln3350His (c.10050A>C) pathogenic?

BRCA2 p.Gln3350His (c.10050A>C) is classified Uncertain significance in BRCA2 (ClinVar, Multiple submitters, 2 submitters; last evaluated 2019-03-18). AlphaMissense: ambiguous (0.5567); Absent from gnomAD v4.1; Associated with hereditary breast ovarian cancer syndrome.

What condition is associated with BRCA2 p.Gln3350His (c.10050A>C)?

BRCA2 p.Gln3350His (c.10050A>C) is associated with hereditary breast ovarian cancer syndrome, hereditary neoplastic syndrome (ClinVar).

How common is BRCA2 p.Gln3350His (c.10050A>C) in the general population?

BRCA2 p.Gln3350His (c.10050A>C) 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.Gln3350His (c.10050A>C)?
